Been meaning to make something like this, where every day has a list and I can swipe through days. I want uncompleted tasks to be moved to the next day at midnight. Finally, I want default (repeating) tasks every day or every week, which don’t carry over.

Been too lazy to make it myself so right now I have a daily todo list template (text file) that gets copied to $(date -I).md a month in advance. I keep a few days open in nvim tabs and access them on my phone via ssh/termux. Then the cronjob archives old lists. Kludgy but been using it for years.
