Improvement Roll appImprovement Roll is Writing tool that is open source under the GPL-3.0-only license. Inspired from "rolling" threads on 4chan. You can create category of tasks that you want to do (in no particular order).
Then press the button and it will randomly give you a task to do from said list.
You can also sort tasks in a category by how long it would take to complete them and randomly select based on time.
