I am the (non) maintainer of mod_qpractice, and I had thought about mentioning it in this thread. Bringing it up to date is just a matter of developer time, but that time is probably measured in at least some weeks and I have been doing other things. I have been back to experiment with it
https://github.com/marcusgreen/moodle-mod_qpractice/tree/bycategory_working and made a commit about a year ago.
Which was code to allow the selection of questions by categories and I think that branch works with much later versions of Moodle.
I would be very supportive of anyone who would like to work on it, or anyone with funding to pay for its development via my employer Moodle partners Catalyst-eu. This plugin, like Student-Quiz fits very well into the core concepts of Moodle.
Sali mentions the use of AI, and one of the things that has distracted me from qpractice is working on my AI Text question type which has got a lot of interest from a lot of places and that has been occupying my time. I can imagine incorporating AI features into qpractice, but I have more imagination than time to turn the ideas into good code.
One day I hope to retire so i can spend more time with Moodle
