How about a way to allow deletion of files without putting them into the Rollback recovery area. There are some file you know you will never want to recover, or you want to recover space without resetting the baseline.
Specifically, my wife was attempting to delete Sims3 (a really big program) from her Rollback 9.1 system, after taking a backup, to recover space. After deleting 30G of files, she only picked up 3G of new free space. Emptied the trash can, no help

. Why, because the other 27G had been put into the hidden Rollback recovery area. She did not want to reset baseline, but had no choice to recover the other 27G.
