Sixteen actions, one package.
Install GainKit Plus too and every GainKit in the project gets its track's name, colour and icon. Run it once and it stays on, or set it to start with REAPER and forget it.

- GainKit Plus — names, colours and icons on every meter; the master shows the project's name. It also runs the long-view arrow on GainKit and the Filter.
- ReaKit FX - Start with REAPER — one press: GainKit Plus and Floatter on at every launch from then on, the seven set to open in the mixer strip, and the offer of a faster meter refresh for snappier strips.
- GainKit Plus - Start with REAPER — starts only GainKit Plus with every launch. Run it again to stop that.
- Insert on selected tracks — adds GainKit to the top of each selected track that doesn't have one.
- GainKit first in every chain / first on selected tracks — moves GainKit to the top of the effects on every track, or just the selected ones.
- GainKit last on the master — a final VU after everything else.
- Copy look to all — one strip's look on every GainKit at once.
- Reset all gains, All MONO, All STEREO, Bypass all — the whole session in one press.
- Remove all GainKits — asks once; Undo puts them back.
- ReaKit FX - Add a track with all seven — a new track with all seven on it, their windows open side by side. One undo step.
- ReaKit FX - Dock following the selected track — the selected track's effects in a dock, whole and working (below).
- ReaKit FX - Docker tabs off-on — REAPER's tab bar off for every docker holding one window, so the dock gets that room. Run it again and the tabs come back.

Plus off (top) and on (bottom). On REAPER 7.81 and later GainKit reads its track's name from REAPER itself; Plus adds the track's colour, the icon, and the project's name on the master.
The selected track's effects, always in view.
Run ReaKit FX - Dock following the selected track and the effects on the track you select open in a dock, whole and working. Click another track and the dock shows its effects.

Select a track (1) and its effects open in the dock (2), side by side in the order of its chain, under the bar (3).
It follows your selection
A track without any of the seven keeps the last ones in view. PIN keeps the dock on one track, or the master, whatever you select.

Double-click a name to dock it
With GainKit Plus running, double-click a plugin's name at the top of its own window and it moves into the dock, on its track. Double-click it in the dock and it pops back out into its own window.

Right-click to add one
A dim button on the bar is an effect the track doesn't have. Right-click it and it's added to the track: GainKit at the top of the chain, the others at the end.

The bar

The track's number, icon and name, with its colour as a stripe along the top (or a band across the bar). A chip for each effect, in the order of the track's chain: a lit one is on the track, a dim one is not. Drag a chip to move the effect in the chain, or a dim one in to add it at that spot. Two close icons shut this track's floating effect windows, or every track's. STRIP puts every one on the track side by side, as many as fit; the arrows, a chip or the mouse wheel over the bar bring the rest into view. The pin keeps the dock on one track. SLOT scrolls every mixer strip on screen to the same effect at once: pick Top, Slot 2 and on from its list, or turn the wheel over it. The chevron folds the bar to a thin handle, and the X closes the dock.

SLOT: Slot 3, Slot 5, then back to the top, on every strip at once.
Click the name to rename the track right there: type, Enter sets it, Escape puts the old name back.

The gear and the icon picker
The gear holds the bar's options: the track number, the track icon, the colour style, full or short effect names, whether a double-click pops an effect out, the fold, the colour on the folded handle, and whether the menu stays open until you close it.

Click the track icon on the bar, or Pick a track icon in the menu, and the picker opens: REAPER's icons sorted into groups, Drums, Guitars, Bass, Keys, Synths, Strings, Brass, Winds, Vocals, Mics, Buses, FX, Rooms, Marks, Folders, with our own icons in them too and a few groups of their own. Groups have groups inside them: click Drums and a second row shows its parts, Kick, Snare, Toms, Hi-hats, Cymbals, Overheads and kit. The categories sit in a row of pills or in a list down the side. A search box, a size slider with the names under the icons when they are big, the arrow keys move a highlight and Enter picks it, a click sets the icon in one undo step, a double-click sets it and closes. + Folder adds any folder of icons of your own and each of its subfolders becomes a category; + Group makes a group of your own, and a right-click on an icon puts it in a group or marks it a favourite. Favourites and Recent get their own pills, an icon another selected track wears gets a thin outline, "All selected tracks" sets every selected track at once, and the window remembers where you left it.
Icons follow the track colour, in the gear menu (off to start): a coloured track wears a copy of its icon painted in its colour. Change the colour and the icon follows; remove it and the plain icon comes back. One copy is made per colour and icon for the whole machine, so every track and project with that pair shares it. With it on, the picker's grid is drawn in the track's colour, so you see the result before you pick.
The ReaKit FX track icons package brings 104 icons of our own: drums piece by piece and overheads, percussion, keys and synths, guitars and basses with their amps and a DI box, strings, brass and winds, mics, vocals, buses, the common effect types and more, with a dark outline so they hold up on light themes. They sit in a folder of their own inside REAPER's track icons: the EON category in the picker and in REAPER's own icon dialog.
The menu and the picker use ReaImGui; without it the gear shows a plain menu and the picker row opens REAPER's own icon dialog.
Docker tabs

REAPER's tab under the dock, then hidden.
The dock comes with GainKit Plus and runs on Windows, with js_ReaScriptAPI from ReaPack. Run the action again to close it. With GainKit Plus starting with REAPER, the dock opens again if it was open when REAPER closed.
Every window opens the right size.
REAPER often opens a plugin window too small, or squeezed. Floatter opens each of the seven at the size it's drawn for, every time.

Saturation as REAPER opens it, as Floatter opens it, and Floatter's panel for that window.
It works on any JSFX, not just these. Drag a window to the size you like, click Capture, and it opens that way in every project from then on. One dial scales every EON window from 75 to 150 %, for a small laptop or a big screen.

Tukan's Blue Compressor, a free plugin by someone else: how it opens, and after one Capture.
Floatter is free and comes from the same place as the seven. Run ReaKit FX - Start with REAPER once and it's on from every launch after that.
Free, all seven.
