As a fellow ADHDr, I've found that I lose track of the entire task tracking system if it doesn't remind me of its existence. I recently wrapped the taskwarrior CLI with some bash and zenity popups that run on crob jobs to ask me what I'm doing and its proven quite effective at getting me to stay on task and log what I've been doing via timewarrior. Not sure how easy that is to do in a web UI, but if you find a similar struggle, it might be worth a shot.
