I have quietly updated the application. It is now called ASK_Palette. The new name reflects the fact that it is now also capable of directly launching AppleScripts and Shortcuts as well as Keyboard Maestro.
If you check out the manual, there are some instructions about migrating your palettes to ASK_Palette from KM_GridPalettes. You can copy relevant resources without actually getting rid of KM_GridPalettes so you can test this new version without totally committing yourself. You can continue to use KM_GridPalettes. But unless I have introduced some bad bug, it is a superior experience even if you do not bother with the AppleScript and Shortcuts new feature.
Here is the link to the web page to download this application.
I am applying to become an Apple "approved" developer so that you don't have to jump through all the hoops and warning about an "unauthorized" developer. I plan to make a fuller announcement later. But I would like to have a few folks give it a try and offer feedback before make a more public announcement..
