I would really like to see the Tools -> System Restore screen display the size of each restore point.
When I am running low on disk space, I use CCleaner and Tree Size Free to determine which files to delete or move. CCleaner gives me the restore point information but not the size. Tree Size Free gives me the size but not the information.
If I had the size of each restore point, I could decide whether deleting some would give me a decent amount of space or, if not, I could choose another strategy for freeing up space.
