As discussed so many times during the last months, each and every suggestion is always taken into consideration, but the one and only priority we have right now, is to release GSX for MSFS and THEN we might start looking into new features again.
About the crew boarding or not, it's not true that only "developers" can use that, it's just a matter of setting a couple of documented L: variables, which can be done for example with a couple of lines of FSUIPC LUA, or Linda, etc.
I've seen others post about bus way points and what not
Same as above. We released the latest FREE major update only 2 months ago, but now we just can't add anything new, and we must focus on releasing on MSFS.
