Been using this app for SSH and it's been amazing.
Side note (not the most optimized way), but want to run something in the background?
$tmux
$[run command]
$shift (volume down) + B, then d (detach virtual term)
command is running in tmux in background
$tmux attach (to get back into the virtual term)
See their docs obviously.. but using a mobile terminal I've been using this primarily for my tasks
