I have similar question as this one, but I wonder is there are an possibility to filter sessions by name?
Maybe use fzf on top of sessions list?
As the result I want to open sessions list via CTRL-b + s (how I can draw button here by the way?), write rust and sessions should be filtered.
You can try changing the binding in your .tmux.conf to:
bind-key s split-window -v "tmux resize-pane -Z ';' \
list-sessions -F '#S' | \
fzf --reverse | xargs tmux switch-client -t"
