As tmux can be extended with plugins I'd recommend to check through this list and see if you find something useful:

As a neovim user I can also very much recommend this vim plugin to seamlessly navigate between tmux panes and neovim windows:

This is a killer feature IMO. Bind the ctrl-hjkl in vim/neovim for navigation and go between vim panes and tmux panes transparently, beautiful.
