Basically I want a way to plan out my routine and stuff to accomplish on days of the week, like do X on Friday. I tried Planner but it seems to not have something like my latter example.
If you like command line: TaskWarrior has due and recurring tasks and weighted priorities and more.
There are also some frontends under Tools, search for GUI, but to me they are more cumbersome than CLI. If you're into Vim then vit might come handy.
