I've just been swamped since getting back from my month off, haven't had a spare minute to work on it.
I'm loathe to push it up to github as-is, as it's still pretty sketchy, a lot of code from the original plugin needs to be stripped out, I haven't gotten 'click cell to add event' going yet (not hard, just haven't had time), so there's just the main "Add" button, etc. It's still *very* much Work In Progress.
However ... I'm probably at the point where having someone actually testing this for real would help, and would give me incentive to find some time for it.
So I'll push it up there for now ... although Rob and I have discussed making this a paid plugin which wouldn't live in github. We're considering charging a little (like a shot or two of Jack Daniels) for some of the more advanced plugins, just to help recoup the development and support time. But I suspect any such plugins will spend some time in github, during the development phase.
I'll do it now ...
