True. What suits you may not suit me. I've had a chance to look at Trello awhile back. My first impression was that I like how it categorizes items or tasks, but I felt the whole structure was a bit "rigid", and that there was no room for "imagination". Probably because I'm a writer and more of a free-spirited person. :) By the way, may I ask what industry you're in? Are you an engineer/developer (just a guess)?
Actually I'm a writer on the side as well. I create a new board for each project, with headings -to be done/ redrafting/ Done. Then I also have an uber board where I can see all of the projects that I'm working with at once. On my weekly to do I put the project I'm working on It's quite flexible because you can move things about, add lists, add new parts to each bit. But it may not work for you. It's good to be creative but I find you need the structure in order to create.
