-- The separator options should go back to the defaults ( →, ← and | NerdFont characters) if you close all tmux sessions (a full restart)
+- The separator options should go back to the defaults ( →, ← and | NerdFont characters) if the options are unset and you close all tmux sessions (a full restart)
 - Both the `@rose_pine_window_tabs_enabled` and `@rose_pine_bar_bg_disable` operate like the separators.
 - The `@rose_pine_width_to_hide` and `rose_pine_window_count` settings do not refresh automatically. They need to be refreshed manually, their current state is discussed [here](https://github.com/rose-pine/tmux/issues/10).
 
-> 5. Currently working on more modularity and powerline aspect toggle. Will try to enable NerdFont substitution
