Regarding the prefix key, I agree CTRL+R may not be the best default choice. But if it is easy to change then I think it is OK. One of the first things I do on a new system with tmux is remap CTRL+B to CTRL+A, as a screen hangover and I think it is more ergonomic anyway. Though it means I've completely given up using CTRL+A / CTRL-X for incrementing / decrementing numbers in vim. I can't think of any programs that have an important use for CTRL-B, that's the tradeoff between uniqueness and usability I guess. I don't think there will be a choice to keep everyone happy or that is totally conflict free.
