I raised this as a Ticket a long time ago, figured I'd put it out in the forum.
It would be organizationally handy to be able to create our own Collection categories, the same as we can with Projects. I assume at that point we would also need to be able to organize Projects within Collections. Right now, Collections seem pointless.
Assuming that happened, it would also then be useful to be able to select a default Collection when starting TC, or at least have TC start on the last-used Collection.
Whether or not Collections change, it would be equally useful to have the same default options for Projects.
