I've been trying to get into using Trello more often. Usually I'll set up checklists for subsets of tasks and cards for larger projects or meetings (so I can add separate notes, files, etc.). It works pretty well. Just drag 'finished' cards into a 'Completed' pile or similar, check off items on a list, etc. Also easy to add people in to a board as collaborators, for instance if you need a manager overlooking your progress or teammates to vote on X task (maybe prioritize bug-fix, etc.).
