I just changed the template to "Arctic" [1]. I like it though this is more or less just to test it, it's not a final decision. I'd like to get some more feedback about the template question.
Unfortunately, the author of the Arctic template won't maintain it anymore in the future but since it seems to be widely on the net, maybe someone else will continue maintaining it. I like that it has a sidebar which is quite flexible. At the moment, I just put a simple list of the categories in it as a simple navigation. Though we could change it later.
Yes, organisation is better and sidebar is better. Don't like it being unmaintained though. The docuwiki template library seems to list a version that templates are compatible with, does this mean that templates have to be updated each time docuwiki is upgraded?
And again, this is just a test, I'd also be ok with the Vector template.
Looks suspiciously like the Geany website, thats why you like it? :-D
Did you find any template that limits the max-width?
