I’ve recently started using a kanban board which has been working well for me.

There are several options, I use obsidian for this because I can easily make a task into a note for further details.

Not FOSS of course but the .md file are easy to access and backup and i use the self hosted live-sync plugin to sync between 3 devices

By zero maintenance they mean you don’t even have to hit the update button. It all just happens automatically. Many Linux users won’t like that but many windows and Mac users will.

They advertise as being zero maintenance which is a huge deal with many windows and Mac users than don’t want to think about the tool itself, they just want to use it. From the site:

What’s the difference between Vanilla Kinoite and Aurora? Vanilla Kinoite is a very stock experience. Aurora includes many enhancements and tweaks, like included drivers for various printers, network adapters and more as well as included codecs. Aurora also features tweaks to enhance your battery life on a laptop.

If you don’t want to think about your computer and just want a tool to use there is Aurora. It’s a variant of fedora but it uses an immutable file system which makes it super stable and reliable. If there are any issues you can easily roll back the entire os to a previous version.

This is true of all fedora atomic desktops. Aurora is a variant that takes it to the next level by making all updates and everything require as little human interaction as possible so you don’t have to worry about how the computer runs and just use the computer for your actual tasks.
