I love rethink but stopped using it on my up-to-date GOS. It randomly stops and no app can reach the internet (or me), randomly it doesn't obey the split tunneling rules or doesn't forward the connections to the tunnel at all (thus blocking all internet if wg proxy is enabled), and couple of other things.

I'll check Rethink again because all in all it's a fantastic software, just doesn't work very stable for me.
