Apart from the "Info" macro I also often use the "Note", "Tip", "Warning" and "Code" macros on a daily basis. These are not in the "Insert More Content" drop-down list, so I always have to 1) choose "Other macros..." and then 2) type the name of the Macro (or the color) in the Search field.

I never use the "Status", "Gallery", "Table of Contents" macros, or if I do, I do it so seldomly that I'd be OK with choosing those via the "Other macros..." options.

I'd like to see a possibility to edit which macros are shown in the "Insert More Content" drop-down list.
