Since we've now entered the realm of pop-up tools for selected text, it would be nice if there were options for that feature. (I use PopClip to give me a similar popup with very customizable tools universally on my Mac.)
1st - Thank you for providing an option to turn it off (Preferences>General>Other). I think I will find the tool quite useful at times, but those who don't highlight will appreciate being able to disable it.
2nd - Add a user-option to add more tools in the popup, since it's right there anyway.
+ Copy to Clipboard (hold shift for Copy as Citation)
+ Add to Stack
+ Search for Word/Lexeme, etc.
