Well, i love it. Its a great way to organise my endless daily mind jottings.

I have made it into a quick little desktop (fluid) app with some minor css changes to help it blend in a bit

Heres a screenshot: http://www.webnibbles.co.uk/dropbox/workFlowyFluid.jpg

If you are interested in running this standalone (OS-X) you can get the app here: http://www.webnibbles.co.uk/dropbox/WorkFlowy.app.zip

Or you can get fluid from here and give it a go yourself: http://fluidapp.com/
