Entries on planning:

I keep a task list in a todo.txt format in Nextcloud. They are simply kept as two text files, todo.txt and done.txt in the root of my Nextcloud user directory.

Some clients already have the option to move tasks from todo.txt to done.txt when you mark a task as done. However, I would prefer they stick around in the todo.txt for a while, in case I change my mind.

At first I thought I'd just write a script to run as a cronjob on the server hosting Nextcloud, but that won't work with syncrhonization, as it won't let Nextcloud know the files have changed. I then thought there must be an API to read/write files to Nextcloud, and then quickly realized that this API is WebDAV. So, I should be able to make a Python script to do this, using requests. A more full-featured WebDAV library would be overkill for this.
