I don't know how much demand there would be for this sort of thing, but this is what I wish for the most on the RB.
1) Power supply voltage reporting in system/health on all models
Reason: I have a lot of solar powered RB out there, and monitoring battery level with The Dude would be just awesome!
2) Have an option on the higher end RB's (433 and up) for a fiber interface instead of ethernet.
Reason: I lease space on several mega-toweres, and with 100KW of RFI next floor up and extreme temperature differences and moisture, ethernet just doesn't cut it. I have had ports go dead with just 6 ft of shielded cable on it. I also tried feeding my APs with fiber up the tower running through a fiber converter at the top, and after climbing 500 ft several times just because of kaput ether connections we went back to a wireless feed. An all fiber RB433UAH would be just the ticket I think.
So what is everyone else's thoughts on this?
