List of categories seems to be static

[benoit74]

The list of categories seems to be static, e.g. it misses at least phet, video, iFixit, ... and blank category (more a library problem, but we need to be able to search these ZIMs as well).

Do we want to make this list of categories dynamic or should we simply update the list before each release?

Updating the list before each release allows to continue to transform the OPDS category (e.g. stack_exchange) into a nice looking label (e.g. StackExchange).

Making the list dynamic allows to not care about updating it and being very reactive to library changes. It more or less forces us to stop transforming OPDS category into nice looking label.

But this transformation of OPDS category is anyway a bad idea from my PoV, we should represent the category as is stored in the OPDS catalog, and AFAIK nothing forces us to have ugly technical categories in the catalog / ZIM (this needs to be answered / solved in kiwix/overview#104).

From my PoV, making the list dynamic is in fact mostly mandatory because we have old devices in the wild, stuck on old iOS versions and hence stuck on old Kiwix app versions. If the list is not dynamic, it means the app will never update its categories ... which is really bad.

Should be (mostly) dynamic, via https://kiwix-tools.readthedocs.io/en/latest/kiwix-serve.html#catalog-v2-categories. But we can rely on libkiwix or/and cache if offline.
