You likely know this, but in case you don’t: Termius makes it easy to use “mosh”, which makes your connection resistant to network drops and resumable. I am experimenting with it right now. Once you install mosh on your serve, click the “mosh” setting in the connection settings in Termius, and you are good to go.

Ive been using mosh + tmux to really keep it persistent between clients.

The only thing I need this point is a push notification when it needs an approval or it has stopped.
