I have to say that it would be nice if the sidecar functionality was available in the free edition. I don't want to try the free version because I'm unsure of the effects that renaming will have. I'd be afraid of losing potential customers because they didn't know about the renaming. I will still buy the Pro version because I definitely need somethings like this and this looks like a nice project to support.

p.s. is it possible to upgrade to Pro Unlimited if I like the Pro version?
