So please, post here task/project/todo management software that you found really nice and useful. That have tags, maybe trees, maybe something else. CLI, TUI or GUI.
I like taskwarrior with karmawarrior (gamify tasks) because it's more like chatops, perhaps you can create a bashscript that adds he taggs automatically?
I love tiddlywiki with markdown plugin, there are also a few task manager addons. Lately I've been eyeing obsidian which is a gui on top of a directory of markdown files. There is talk about using taskmanagement flows with obsidian (so making it a bit simpler then org-mode), there are various solutions and add-ons and supposedly first class support for tasks in Obsidian 0.12 although I haven't found it yet.

Or just using my s-pen/s21 to scribble a short todo list in my own handwriting, or just use paper
