So far I’ve only themed GTK with Oomox, Rofi, Kitty, and CSTimer. Currently priority is QT Flatpaks, where It seems the only option is Kvantum.

Vikunja (hosted on tchncs: https://todo.tchncs.de/) is great for tasks but I haven’t tried using it for a grocery list.

+1 Kdenlive is great and its open source software from KDE

It’s not much but I will post later

I’m currently using the Hack font and a color scheme I made by editing Material Darker. I’m happy with the color scheme but I’m having trouble getting certain parts of my desktop to follow it.
