Zone2, the time tracker for Mac

I just bought this app, and pretty much immediately gave it a five star written review on the app store. I have been desperately searching for a tool that allow me to be able to quickly switch between projects, record irregular intervals of work for a given project, and export that info as some sort of document (CSV preferred). This app meets that need with a great UX, and without all the unnecessary fluff of expense tracking/project management that others seem throw in.

Is there a way to archive projects? I would like to use this for my work, but I wouldn't want to have a longs list of past projects in the drop-down.

Also, there aren't tasks, right? Sometimes it would be nice to have several tasks under a project.

One thing about things going into the Mac App Store is that there is no trials. This looks like it may be great for my needs but there's no way to try before I buy... now, it is just $3 so, why not?
