I am a heavy user of bandcamp, but I find their notifications...lacking. I ended up taking their emails, categorizing them, and putting them in RSS [1]. This has cleaned up my notifications and makes it much easier to follow artists and to easily separate new releases vs news/merch/...
Also, I find bandcamp's wishlist manager to be severely lacking. I use the wishlist as a queue of things I need to check out or have already checked out (and may not have liked). But, it isn't really meant for having 1000s of albums in there.
So, I wrote a wishlist manager [2][3], which lets you organize, comment, rate, and listen to your wishlist.
I spend a quite a bit on bandcamp, especially since many of the bands I listen to are only available on bandcamp (no streaming services!). While I am glad it hasn't been enshittified by the acquisitions, I do think there could be a few small UX improvements.
