Greenshot updated from 1.2 branch at commit e9ab99c5acc99785cc5045b4b5493c9b6504d016 This solves #1341 and #1079 for allowing support high DPI monitors. Additionally, the following were implemented: - #748 - Objects can be saved to file and loaded from file via menu - #676 - Keyboard shortcuts added for 'Save and close' (Alt+S), 'Close' (Alt+W), and 'Close and cancel tasks' (Alt+C) - #1189 - Editor opens sized to image. Can be disabled via Greenshot ini with `MatchSizeToCapture=False`
