Feature: Add a button for "Copy To Clipboard"

[shafique-md18]

I use this app daily, and it would save a lot of time if there is a shortcut button for copying to clipboard.

It seems that no one is maintaining this project, I would be happy to contribute for this change if it will be merged.

Thanks for the offer! I'll merge it in if it works on all major platforms.
