Basj,
I find these documentation pages mostly unhelpful since they simply repeat the text contained in the application without edification. It's as if someone wrote the in-app text (the briefest text practical for the UI), copied it, and inserted it on the webpage "documentation" page. Repetition isn't help. The documentation entries should be expansive.
For example, I find no clear, detailed explanation of the intent of and interaction between Block / Allow Applications, Custom Rules, and Automatic Window Grouping. The latter is a section that doesn't provide a clear way to add an entry other that the cryptic "...from the Groupy menu on the Groupy bar."
I struggled to find documentation entries for the Groupy bar, other than on the General tab where it mentions the bar becomes visible when hovering over title bars but is only available on ungrouped windows and, potentially, windows without a custom title bar (some gotchas there😛). Experimenting with a few applications revealed the trick, but I shouldn't have to hunt and peck. The help on this feature is lacking clarity and a useful example. It could be improved.
Consequently, I would suggest that any functionality referenced on one page be linked to the corresponding feature page and section. Internal cross-reference navigation would be useful.
At least, for my experience, I now know where the "bar" and associated menu can be found. In fact, it's not dissimilar to Groupy1.
Maybe you need users smarter than me🤣
