Cons
Con Scrolling window capture is only working in Internet Explorer
Con This version only works on Windows, not Linux nor Mac
However, the same author now has a separate version of Greenshot for iOS, which is available (for a small fee) in the Mac App Store at https://itunes.apple.com/us/app/greenshot/id1103915944
Con Uninstaller removes nothing
After uninstalling removal of almost every file manually from different directories is still necessary since the actual uninstaller only displays "other files still remain".
Con Minimizes after each paste
You have to activate it twice to paste twice.
Con Does not support HDPI displays
On high DPI/resolution displays, the UI is very small. Practically unusable.
Con RTF bug is still present in latest Beta version
You can turn on the option to draw RTF text in the clip list, but it no longer works in Windows 10 Ditto (64bit), and the latest Beta version available today - which claims to have fixed the bug - still has the same bug. It will no longer draw RTF text as-is in the clip list.
Con The UI is very confusing
Con Can't use any shortcut you wish
Anything with spacebar, windows key (that the system also uses) is not possible.
