I tried plain-text task management too since I use plain-text formats for various things in my life anyway, but I could not get it working as good as a to-do app. My final outcomes are: - capturing tasks/todos on the go is a huge problem with plain-text. - never syncs properly. - proprietary apps (unfortunately) works out of the box and without a hassle or personal infrastructure concerns. - being able to capture using a web browser makes things very easy because sometimes you are not even allowed to install some kind of syncing solution to company PCs.

Maybe I'm dumb but another thing I never understand is how the hell you think org-mode is the best way to do this? An org document is one of the worst things I have seen in my life in terms of readability. How do you read this and properly interact with that mess? I am really eager to understand...
