Hey folks, in case you want to use TPM while you wait for this PR to get merged, I've got it working on my fork https://github.com/lucasfcosta/catpuccin-tmux.

I also use the following plugins, which means you'll probably have to alter the status bar if you don't want them:

# plugins
set -g @plugin 'lucasfcosta/catpuccin-tmux' # tmux theme <3
set -g @plugin 'tmux-plugins/tmux-cpu' # shows cpu status in status bar
set -g @plugin 'tmux-plugins/tmux-battery' # shows battery stats in status bar
set -g @plugin 'tmux-plugins/tmux-online-status' # shows internet status in status bar
set -g @plugin 'tmux-plugins/tmux-pain-control' # better control of panes
set -g @plugin 'tmux-plugins/tmux-resurrect' # persists sessions between shutdowns/restarts
set -g @plugin 'tmux-plugins/tmux-continuum' # continuous save/reload sessions
set -g @plugin 'robhurring/tmux-spotify' # spotify songs

Alternatively, you can just add all these lines to your .tmux.conf and install of the plugins to get the same statusline as me.

I'll work on this after having merged #11, I'll try to work from your PR branch. Thanks for the idea!

I finally got to this, apologies for the long wait.
Hope everything works.
