if you know any scripting language, Growl is a great way to work it
write a script (use the included forum growl as a template, if you need) that will notify you on update and also write to a log file so you can check it when you've been away.
I haven't checked the app you linked (will do so presently) but I know you can achieve what I think you described using Growl and a bit of scripting. Of course, if scripting isn't your thing, then you're better off with a complete solution, which I gather this app must be.
