Thank you for the new option to put a custom menu of macros into the menu bar and for adding SF Symbols to the Icon Chooser. Both improve the experience of using KM by expanding how macros are accessed in action.
While you've fully opened the doors to having any palette design imaginable using the Custom HTML Prompt, in practice, for me, it's unlikely to be accessible as my desire to have palettes be what I'd like them to be isn't great enough to get over the mountain of learning HTML. And, from the lack of examples, I don't see anyone else taking on the challenge.
Therefore, I request you give some serious attention (for Version 11) to adding options to the existing Palette Theme Editor, such as radial Menus and other suggestions made within the forum.
One thing, in particular, that would be very helpful would be to allow text in addition to icons to be made and used in the Icon Chooser.
Thank you again for your indispensable addition to the Mac!
