Multi level grouping

[SimJoSt]

We use multiple prefixes in our Slack channel names. It would be great to group the second level prefixes as well.

p-customer-project is a often used scheme in our company.

Great to hear. Just stumbled upon this again. Is there a timeline for the development?
Unfortunately, I cannot contribute with a PR.

Hi.
Thank you for the great extension.

My fork now supports multi level grouping up to level 4.
I haven't written any tests and the code isn't refactored, but if you'd like, you might be able to use it if you build it.

Thank you so much for your contribution! Don't worry about the tests - I can add those later. I'm just grateful for any help with the implementation.

I've tried it locally and it works great!

If you could create a draft PR, our CI will automatically build packages for each vendor, making it easier to verify changes during development.

One small suggestion though - I think it would be nice to have this feature configurable through a popup when clicking the extension icon (similar to how Dark Reader works). We can keep it enabled by default since it's a useful improvement for most users.

I can handle this configuration UI part after merging your changes.

Thank you for your wonderful suggestion!
It would be nice to have settings.
I will send PR in the draft, so I would appreciate it if you could modify it as you like.

I am always grateful.
