The app looks great, congratulations on the beta. Will continue testing it, but it connects well and works quite fast. I mainly use Termius, but the tmux support here is interesting.
thanks. there isn't a multi-pane view currently. i chose to show one pane at a time because of the available viewport on phones. you can switch between panes using the pane picker in the bottom sheet, but i'll consider adding that if there's enough demand.
