Simply Wonderful!
This is obvious one of the many AppStore derivatives of the famous ClipMenu app (open source now). But, this one is actually done right! A wonderful less is more design from the original app which I had to abandon due to lack of update and compatiblity issue. Great work dev and please keep it updated!
BTW for clicking the menu to paste directly, you need to check the “input cmd+v after menu item selection” in the preference, then select the application script folder as requested. This actually is due to Apple’s security restrictions I believe. The dev should consider adding an instruction to the website Q/A section.
