Please make the HUD editor work according to Windows standards. Shift-click should select multiple items. I'd also like to be able to copy or move multiple items, not only delete them. Tabbing between items doesn't seem to work (it might work in some places but focus gets lost-this seems to be a PT-wide problem dating back to PT3 (at least)). Alt does absolutely nothing - even if you insist on putting functions (which are normally under menus) to be accessed via an Options-button, I should be able to Alt-Apply or Alt-OK.
Also enable inserting a group of stats to another group, either via import or just copy pasting. For example I might have two popups which I wish to combine (or move some data between the groups).
EDIT Before you ask why I'd like to copy items: I'm mainly interested in text fields, although I could see copying stats also during designing a group (or as a way of moving stats between groups).
