Opus Quad: Edit Rating, Matching Tracks

Working with the OQ and really enjoying it so far. I have two questions:

1. How can I edit the rating tag of a track (out of 5 stars) on the OQ? I can find where it's listed easily enough (the info 'i', top right corner), but am at a loss when it comes to figuring out how to adjust that value.

aside: I've read elsewhere that the cdj3000's lack this functionality, so is that a similar situation here? Hopefully not! It's a very useful feature for me as I like having complete and orderly tags and rating is one in particular that benefits from on-the-fly tweaks. 

2. How to label/tag/identify (not sure what to call this action) matching tracks in the OQ UI? I know how it's done in rekordbox: the little 'match' button on the right side between two players. That isn't as useful because it would be during a practice session that I think "wow these tracks really go together!" and not during a prep session where I'm mainly concerned about cues, bpms, beatgrids, and phrases.

I feel like I've scoured every inch of the settings and the manual and haven't found these actions. If anyone knows how to perform them, please enlighten me!

bonus question: the 'auto connect' parameter in network settings does not seem to work, I have it enabled but still have to manually connect to the network every time I turn the unit on. I'm not exactly sure where to report this issue, but I'm putting it here just in case the right person might see it.

cheers
