Great simple flashcard app that appears to do exactly what I want with none of Ankis buggy behaviour except... it appears as a small portrait borderless window in the bottom centre of my screen that I can't move, scale or tile with the very bottom edge disappearing off the edge of the screen. Maybe it's a bug that'll get fixed later. Uninstalled but I'll try later versions. Also it's a flathub version. Even though I have several flathub apps installed this very simple app takes a whole Gb of space. Update: I had to reset my system so tried this again. Same. No way to exit the app. Had to use xkill. Uninstalled again. Update March 14, 2024. Tried again. Now it doesn't even run (or appear to run). Mint XFCE 21.3. Not sure what it was doing. Used Timeshift to go back just in case. Beware!
