After making a few changes on a screenshot, if a different picture is selected on the "Thumbnail Panel" there will be shown a pop up with a few saving options, a combobox and a "Ok" button.
This topology requires too many clicks and readding everytime one want to just answer "Overrwrite" or "Abandon Changes" and therefore addition of these two buttons instead of just a "Ok" button could be realy a nice thing. (BUG: if you click "X" to close this dialog the "OK" button function is triggered)
Another more complex idea would be to make a "Auto copy to clipboard when ScreenshotCapture looses focus" setting so that one could take a screenshot, make a few changes (Highlight something for example) , and right after changing application (to outlook for example) the picture could be automaticly saved on clipboard, so one could paste it directly... (At the moment even CTRL+C does not work all the time and one has to go to Edit menu to make a copy... strange...)
Have a great day and thank you for this excelent application
