Not sure if I’m the only one who ends up in this situation, but I often have multiple tabs in my Macro panel, for doing either small, or very specific stuff that I don’t necessarily want to make a script out of. The tabs’ names aren’t explicit about what’s inside and the numbering might get confusing as you can end up with tabs with the same number when you close and open new ones.
How about having a preview of the first line as the tab’s name, like you do for Edit tabs?
As a more general comment, I would love to be able to rearrange tabs (both in macro and and general windows), in the same way we can do with browsers. That would be a big quality of life improvement to Glyphs in my opinion, although I don’t how complex that is to actually implement.
