Having buttons on the GM console would make it easier for GMs to prompt RP stuff like like you say, but I’m not convinced that it should be necessary. One of my main points was not to rely on the GM for RP inspiration. The GM team is great for planning story arc and individual missions, but I think the best way to encourage RP in general is to encourage spontaneous stuff that the GMs might not have direct control over.
Even things that the GM is directly involved in are often flexible. I’m thinking of Act. Ens. Jafar Ironclad’s report last shift of the boarding party he piloted. That was awesome, first of all in how thorough his report was, and second because of his enthusiasm. I think there is lot of wiggle room for role-play that isn’t utilized as best as it could. Ultimately, if someone wants a better role playing experience, he has got to be putting some effort and creativity into it himself.
Having guides to roles and background would definitely help, though, especially newer recruits.
