Rename of screenshots

Hy, i tried to rename some screenshots to remember what they display. Unfortunately after loading pixefy at the other day the renaming has been removed by the system. So as it is difficult if you are in a working environment with 5 clients a day reviewing say 3-10 pages a day it is very difficult to keep track. So having the optiuon to rename the screenshots is a must in my opinion and :-) Feature request :-) having a folder or tagging structure for screenshots would make it even better.

Thanks for your effort

cheers
