Treedome is a local-first, encrypted, note taking application with tree-like structures, all written and saved in your computer
Currently you can only try it by building it yourself, instruction here. https://codeberg.org/solver-orgz/treedome/src/branch/master/docs/building.md But .deb and nixpkgs update is planned to follow suit though! You can also try an outdated one in https://aur.archlinux.org/packages/treedome-bin
Tell me what you think about it!
I've used CherryTree extensively in the past, with the password protection on (encryption). The save time gets longer as the file gets larger, because it's encrypting the whole file (every single one of your notes) everytime. I dislike it and told myself to create a new one that solves it. Then, Treedome was born.
