It would be cool to be able to set custom icons (or choose from a pre-set bunch of icons) for views. At the moment, we have icons for List, Calendar, Board, etc, but it would be great if we could put our own in. For example, I have a list for "Completed Tasks". This gets the same icon as my "current tasks" and "urgent tasks" lists. It would be great to be able to give them unique icons and colours so they are easily identifiable. Like you could have a green tick for completed items, a red exclamation point for urgent items, a stop sign for items blocking others, etc etc.
