I'm looking for a GTD app that best fits the needs of keeping track of a high case load. I'd like something that allows me to have each case listed as a 'project' with sublists for motions, hearings, trial, etc. I've tried noteskinery, which is OK, but doesn't have a desktop companion. I've been trying Things for OS X, but adding sub-items seems complicated (as far as I can tell it can only be accomplished by creating tags for each project), and I haven't yet figured out to make tasks only appear where I want them (for instance, everything shows up in 'Today'). EDIT: I'm beginning to make a little more sense of how sub-items work... If anyone can make sense of what I'm asking, please let me know what you would recommend. I don't want to spend the money on Omnifocus and Things for iPhone just to try them.
