[Enhancement] Auto-hide forum posts from sidebar

[yioannides]

Hello, thank you for your great work! I would like to suggest that it would be better to have all existing posts in a forum channel hidden by default, for example:

Before	After

This is only doable once #142 is implemented, otherwise there's no way to actually browse inactive/unjoined forums.

Thank you for letting me know. What I meant was to have the forum channel dropdown closed by default, as a temporary solution for now.

I can design a mockup for how to interact with forum posts via existing libadwaita widgets, but yes it ultimately depends on what the API you're currently using provides.
