I would also like to add that you can copy an imgur link from this screenshot by right-clicking or similar. GDLauncher had this before they switched to their new launcher and I loved this feature because it's just a quick and easy way to share screenshots

[Pyrotonic1]

I agree. I think Prism Launcher has that feature as well.

I will be working on this in a PR.
