Project Prioritisation

It would be great to create a board view of projects in progress and be able to prioritise with a drag and drop type functionality as with tasks, although the outcome of dragging a project to the top of a file should be a clearly identifiable (and preferably colour coded) prioritisation indicator. We currently have to spend too much time messing around with custom fields and project numbering from 001 to 999. This is time consuming and prone to issues!
