This is likely not a small ask, but I’d love to see a way to add items to the top menu and context menus. This is something you can do with plugins in Vectorworks, and it’s pretty nifty. In Vectorworks, the menu options typically just run some sort of script, which can also include dialogs.
One “simpler” iteration of this might be to just allow adding context menu options to customized components.
If there happens to already be some brilliant way to do this, please inform!
