While that would be cool, adding a section that is actively called "maintained" might make it harder to maintain the list and give the wrong impression to users when they click on projects under the maintained list that aren't actively maintained anymore.

But this years project was indeed very cool, although buggy ;)

Hey, in the end everything worked out 😅 : At least the RIOT part of the project didn't require any fixes for the final presentation as it worked fine under the constraints we set ourselves (Offline behavior -> undefined)

I'll however try to check whether the last minute bug fixes have been properly merged so any user that would be willingly to set up the entire project would be able to properly use it without any major issues.

Might it make sense to split the section into "mainained" and "completed" projects, then?

IMO "maintained" should be the implicit default. does "completed" mean the right thing? maybe "historical" fits better?

Hm I feel "completed" is a good choice. Sometimes you just want to build something and then...it's done.
While "historical" feels a bit like "yeah this is project from before we had a big change in RIOT".

But in the end, both wordings are fine. If we do go down that path, we also need to move the MiniLoon project there.

I think it looks OK.
