I have a few questions here:

1. For the space between windows, what is wrong with window-status-separator?
2. This will break other people's configurations, can you achieve the same thing by modifying your own config?
3. Does setting @catppuccin_status_right_separator "#[fg=#{@_ctp_module_text_bg}]\uE0B4" not work?

Good questions. Let me answer respectively.

For the space between windows, what is wrong with window-status-separator?

If you see the windows under Before heading are squished together and don't look as mentioned in the documentation, and also is different from how it looked previously. Please have a look at the attached screenshots below (look at the red circle).

Documentation

This will break other people's configurations, can you achieve the same thing by modifying your own config?

Can you please explain how will it break other people's configurations? It can be done but it's a too low-level configuration for the user in my opinion. At least it should look like the example configuration.

Does setting @catppuccin_status_right_separator "#[fg=#{@_ctp_module_text_bg}]\uE0B4" not work?

It will work (haven't tried it) but isn't the expectation would be that the right separator should be of the same color as the text background. Same as how the left separator has the fg set, the right separator fg has to be set.

Yep I can see that. If you add set -g window-status-separator ' ' in your config does the same thing happen? See the philosophy doc on orthogonality of features; I don't want to add a feature that already exists in tmux itself.

I made the decision to not do this to increase flexibility. You can have a space or text as the right separator if desired. This change means that those configs will break.

Tmux is generally quite difficult to configure and style. There are things like tmux-powerilne that make it easier at the cost of flexibility. I would prefer to expose only primitive styling in this plugin, with the hope that other things can be built on top of it. For example I'd love to see a "catppuccin powerline" repo somewhere that someone made

I think this makes sense and setting the window-status-separator works the same way. Good call. I'll remove this change.

This doesn't work or may be I'm doing something wrong.

Wouldn't you expect the same color for the separator even if it's a space? For the text something like #[fg=#00000]Text can be added as the separator value.

It works if we make the following change in status_module.conf

If you have a disagreement with the proposed changes then please make the change in my last comment and I'll close this PR. Thanks a lot for your work.
