We are working on it right now. I took a brief detour to write about what we are up to which is now finished, so back to programming.
Right now we have a very "geeky" looking UI with the excitement of a slide rule with a pocket protector - it is strictly functional. If you understand the system, which the current users do, it works well. But if you're in for the first time, you would have a hard time knowing what to do without someone walking you through it. The goal of the redesign is so that anyone just looking at the screen will know exactly what the options are and how to work with the system without any tutorial.
I'm vanishing into a fit of interface redesign for the next 2 weeks, at which point we'll have screen shots and let people in to play with the tools - the context focusing and ActionStreams are especially cool. We're calling it our UI launch, and with feedback from that, we'll role into our full beta launch. We are getting excited about it after a good 7 months of hard programming + a few years of research, which explains my too often mentioning it here (which I'll try to refrain from to avoid being considered a spammer, which is not my intention).
The whole application started because we needed a tool to help my firm implement Lean Management to gain the kind of tranformation that Toyota and many others had achieved, and there were none out there. With Architecture and most service companies, a vast amount of information needs to be organized in the right way to really be lean, so analog methods really don't work well. We tried it first with binders and post-it-notes and white boards but it slowed us down.
"Getting Things Done" is a great productivity breakthrough as well, and when combined with lean, is really impressive - which is what we are doing. Lean helps provide the framework for what to do and how to do it, while GTD helps you actually get it done.
One of the enhancements to GTD that we've got is that rather than think about the next action you need to make, we provide a way to think about the next stream of actions which can can be templated for future use - it has been a great boost for us.
