Hogwild Readability. [...] Appearance. [...]
Okay, now I understand.
The administrator has the option of setting the total width of a DokuWiki page and the width of the sidebar (menu: Template Style Settings). This results in the width of the content area.
One disadvantage of a narrower content area is that there may not be enough width for large tables or images.
The Wrap plug-in can also be used to create two- or three-column layouts.
You could also trick around with dummy images that have no visible content. (However, the dummy images would then have to be hidden on small screens, which is only possible using CSS.)
There are other possibilities, in principle a lot is possible. However, the know-how needed and the effort required to implement this is, admittedly, considerably greater than with classic layouts that are intended for printing.
All in all, I think the layout of wiki.freshtomato.org is well done. From a practical point of view, it is a good compromise that represents a happy medium. I would leave everything as it is. In the end, some things are a matter of getting used to.
However, I would also like to emphasise that I can very well understand and also share your wish for a more readable and nicer looking layout.
But also the simplicity of a wiki already mentioned by @pop, which is also necessary above all for successful teamwork in a wiki, also sets narrow limits and requires unattractive compromises to be made.
