More in mouzerun

The panel has no tabs; buttons are shown in cards by their user-set Group, with six starters in "Starters". The menu command field suggests 27 menu texts in total (e.g. Easy Ease, Time-Reverse Layer, Enable Time Remapping, Add to Render Queue, All Memory & Disk Cache...). The editor also offers 10 colour choices (including No colour) and 24 icons (e.g. bolt, star, wave, camera, scissors). Alt-click can open the editor, run another button, run the button's own Alt action, or for scripts run it with mouzerun.alt set.
