An option to "Keep Changes" when exiting a virtualised browser.

I’ve spent a while this afternoon trying out various add-ons in Ice Dragon. My usual practise is to run Virtual Ice Dragon, try out a few add ons, then restart Ice Dragon un-sandboxed and reinstall the add ons I liked.

What I thought today though when exiting Virtual Ice Dragon (pinching the idea from Toolwiz Time Freeze), is wouldn’t it be handy if I could choose to keep the changes I made while virtualised.

Not sure how pratical/advisable this is though, what do people think?
