New day, new ideas. This one doesn't seem like it would be too hard to implement (but then I know next to nothing about code, so..)
A shortcut command that deletes text from a shape without deleting the shape itself. I know anyone here who uses spreadsheets will be familiar with this ability! It'd just be a neat little time-saving feature that would mean, when deleting large swathes of text, that we wouldn't have to click the group, double click the box, double click/enter to edit the box, ctrl + a to highlight all the text, and then delete to be rid of it.
What would be even better is being able to shift select multiple shapes at once, and then using said command to delete all text within the selection.
