Recently buttons were updated so they can trigger RTS signs, awesome. There's one thing I'd suggest though. Currently, anyone whether or not they have a use flag can trigger RTS and [Message] signs.Maybe make it so that you need a use flag to do it? I think the main point of buttons is that they require use flags, and to have them work with anyone kind of defeats the purpose. I tried making one to get to my underground storage, and recently people have been getting down there by just clicking the button (nobody other than myself have any flags).If not, maybe we could have +buttonrts and +buttonmsg flag which you need for that to work? Separate from use flag, so if you had +use you could use buttonrts and buttonmsg by default. So basically buttonrts and buttonmsg are sub-flags of use; if that makes sense.
