I haven’t seen Our Groceries listed yet. I don’t know Grocy so I don’t know how this one compares, bells-wise, but it’s pretty straightforward, you can share a list with any number of users, and manage/add/edit/remove lists and items via a web app or mobile app.
I’ve sent the devs more than one feature suggestion / bug report, and they were impressively responsive and forthcoming.
I’m just running a pain Linux with the MATE desktop, with increased sizes of mouse cursor and UI elements.
The big thing is using VLC with a wireless keyboard, and using a white sharpie on the keycaps to show the quite customised VLC shortcuts.
It’s been years since I tried Kodi et al, and I always found the actual media playback to be lacking some customisation (eg. audio or subtitle timing offsets).
In lieu of a media database, I simply mark the movie folders with file emblems when I’ve watched a movie or episode (VLC keeps track of partial viewings, resuming where it left off).
