I hacked together a quick TODO list recently. Basically a 'plan for the week' to keep me on track. I just glanced at it now, and I thought it was funny, particularly now that I've added the last two items. :)
First, fix data tier and test. Need transaction context, and providers up.
Then, fix model. Need to transactions up, and persistence mechanisms.
Then, fix import, need to be able to pull in data.
Then, fix UI. Need better support for rendering null types in the GUI.
Then fix export. Able to export for reporting.
Then fix web stuff.
