I hope this is the place we can discuss this :). My opinion: each item should be separately unselected the moment it is transferred (moved/copied). I'm willing to work on it btw.

I'm also for deselecting items when job is started. In the future we could save the item list and recall it with a shortcut.

If you want it, just claim it! Everyone will know that you're working on it. When you're done, open a review.

And if you find something to be discussed, add it to the TODO list.
