I discovered the tool from your Youtube video series. It is awesome! I configured the option to substitute the native snipping tool in Windows 10 but it only works when I try to execute the tool from search/start, and not from the default shortcut that is Windows + Shift + S (it still shows up the select buttons from Windows, but does not open the result in SnipEx).

Thanks for providing a great replacement! (love the auto copying to clipboard)
PS: Would love to see a series on how you developed the tool (I bet there are some nice tricks)
