I've built an awesome billing/invoicing/project management system in a Numbers worksheet, I'm really liking Numbers. One piece I haven't figured out, though, is how to automate the time-tracking better. Currently I just manually enter the hours I work on each project. Ideally, I'd click when I start, click when I stop, and those start/stop times would appear in table cells so I can calculate my hours worked.
I know Numbers '08 doesn't have a macro system, and it's not applescriptable, but maybe there's something clever I could do to get this working? Maybe something with the NOW() function?
