We use Trello for bug tracking, and when we have a bad bug , we can get up to 1000 reports in a single list. When i want to move that column to a different workspace to delete it, (because Trello won't actually let you delete a list of course!) it says 'synching' and then sits there for a few seconds and makes the list reappear. I assume rather than moving the link to the list, it actually moves every single item individually and then times out on the server.
So, if you have 1000 items in a list, how exactly are you supposed to delete it (as you HAVE to move it first) without Trello locking up?
