My official involvement with the project began early this year and I've begun to work more in dealing with such issues. That said, several people have made mention to me their changes not being reflected on the website. The server is supposed to regenerate all updated pages once a day, but this obviously wasn't happening. I've spoken with frik85 about the issue and he's looking into it. For the time being, it's just a matter of manually regenerating the pages, which isn't difficult, but it's something that we need to remember to do.
As for your other proposal, I don't know if frik85 has included such a thing in the new RosCMS he's working on, though if he hasn't, there's another dev that I know who might be able to pull it off.
