GUI buttons for Action groups, screenshot attached

[Einsty]

I suggest adding a row of buttons to the UI to trigger the custom Action groups.

Only assigned Action groups would show to reduce screen clutter. (Not necessary, hiding the bar like NavBall would suffice)

Each button's appearance and behavior could be customized in Action group Editor.

In terms of appearance, Color and icon could be selected. Icons could include engine icons, solar panels, various pictograms etc. The default would be a number icon.

Behavior would include:

normal - press to trigger, icon flashes

toggle - press to toggle, icon stays lit - one press, Action group keeps being triggered, like parking brake. (Long press could behave like normal)

visual toggle - press to trigger, icon stays lit - for actions that are toggles in nature, like toggle engine

If posible, corresponding part would light up when hovering mouse over the button, like stage icons do.

See attached edited screenshot.

I suggest this because keeping track of myriad of Action groups configurations of already launched craft is difficult.

Possibly, more GUI-only Action groups could be introduced this way, partially solving the issue of nearly fully mapped keyboard in KSP.
