Looks good - I like the TUI a lot. The only thing with that type of interface is that there is no chance my wife would use it via the terminal. It would be cool if there was a web UI as well - so other members of the household could access and use it.

If I am the only one who can use it and only from one computer, it would be entirely useless for my needs. I have several computers and also family members who would need access to that data. A Google Docs spreadsheet would be a better tool for my specific needs I think.
