Planners/Scheduling

I've been trying out the CM Organizer from Simply Charlotte Mason and although I do like many things about it, it's not fitting my specific needs. I've seen similar frustrations among other CM moms and am wondering what exactly it is that would make a good planner. If you have any insight you'd like to offer, please do so. I'm going to go have a cup of coffee (in hopes of perking up my foggy brain) and have myself a little brainstorm and see what I can come up with...then ideally, come up with a solution. Eventually I'd like to come up with a web-based solution (and put to use the skills of my past life as a web designer) that I can offer to other CM moms to remedy what seems to be a fairly significant problem (at least in my eyes).
