This is also a feature I would love to see. And multiple selections should be able to be dragged together, not just one at a time.
Additionally while on the subject of drag and drop – it is a bit of an accessibility issue to have drag-drop as the only method of performing a task (I experienced it because of a dodgy mouse, but for anyone with physical disability it’s even more of an issue). A context menu approach would be great to have as well. e.g. I think the only way to delete a time entry is to drag it to the bin – why not have context menu delete and/or highlight and hit Delete key options as well?
