Oh no doubt, things are always improving. While I have not yet used it, happy for the recent json enhancements (personally, I would always prenormalize to standard JSON instead of naively ingesting JSON5).
Datetime is definitely one of my SQLite sore spots, so happy to see improvements there. I have to consult the docs + experimentation every time I need to do something with time manipulation. Even then, I usually left a bit disappointed with the available functionality.
Some text functions like `trim` have been added recently, and there will even be a (long-awaited) `timediff` function in the next release.
