Does Greenshot also have a kind of Library (similar to Snagit Editor Library) where you can make edits/corrections to an earlier made sceenshot?
For example: a few months ago I took a screenshot, and at that time I edited this screenshot by adding borders, speech bubbles, highlights and so on.
But now I need to correct 1 of the speech bubbles.
Can I pick-up this "old" screenshot again, and make changes to it, or do I have to re-start from scratch?
Thank you
