As far as I know, CasaOS (same as removedpit) is installed on top of a default OS install, so you could always access the OS directly to install/configure things outside of it, if the need arises.

I would not say you would be held back by it, if it does what you need. And for what I can see online, you can install any docker container even if it’s not on the default catalog of CasaOS, or access the OS.

If you want to grow your knowledge of how things work, or how to deploy services without CasaOS, you can always do so in parallel of using CasaOS, so I don’t see where the issue could be.

Dislike: there is still no way to group communities into sub feeds, apart from subs, local, all. (and the work around some do of having multiple accounts seems silly to me)
