One suggestion for improvement is avoiding creation of self referential links. For example https://halupedia.com/chaldic-arithmetic has many references links to itself.
Yeah, the way I've been doing it is when I complete an old puzzle I hit back to get to my next "old" puzzle. Still have to keep a tab open so I don't have to click through the pages of puzzles I've completed though.
James May did a car "review" with Margaret Calvert years back in an episode of Top Gear. Was a bit of a departure from regular Top Gear but certainly interesting https://www.youtube.com/watch?v=wTDB3dpe3eg
> Also, I have ADHD. This is probably relevant, but I haven't quite figured out how.
Are you medicated for this? I got diagnosed with AHDH last year. The doctor I'm seeing specializes in ADHD and OCD and they have found in their experience that there are kind of two forms of ADHD. One is the hyper active part giving struggles to focus. The other is a motivation side of it where it's difficult to even get started on tasks. For me it was certainly the latter and the techniques + the medication I have now have really helped me feel productive and motivated again (inside of work and in my free time).
