re: turn WhatsApp off -i can, if don't forget, and more important i should not forget to turn it back on in the morning.
Maybe some automation that disables apps by time would help... But better would be if I could set whatsapp background process priority... but this would require root I guess.
I thought of bridging whatsapp with matrix.org, and use then only the element.io client which works good - it's possible - but requires additional pc to run all the time, not really a solution.
