has not been updated for a full year

This app does NOT have functional consistency.
It constantly stops working/crash on regular basis.
If using on MBP. close lid, then open again, this app literally stops working.
Right clicking on app to quit? Unfuncional. Does nothing. At all.
Only option for you is to launch the active monitor to force quit the app, then launch it again.
Clearly, this app requires frequent re-launch.
There are more apps out which recieves constant software update by developer.

This is an abandoned app.
Spend your money elsewhere.
