1) Select all items/tracks/envelope points (depending on focus) is not including AIs or Envelopes: (edit: Ai's been fixed! still missing Envelopes)
2) moving items should move always both items and Envelopes/AI (not dependent of envelope points do not move with media items):
in my use case i would like that AI's got selected too if the focus in on project. My thought is "move whatever is selected and i am dragging" and not "move from whatever is selected those which media item type is equal to the one i am dragging"
3) same same for changing item edges and offset on AIs, the changes should be done for both selected types:
