Thanks; I'll check that out. - - - Updated - - - Because I live in communist Russia? Oh, yeah, and another feature request, if I can, please. When building my gigantic space station, I have the modules all arrive close to Station before ditching their liquid tanks and engines (so that only the part needed, plus docking ports, are what are actually attached to Station in order to save part count). This means that I have spacecraft hanging around basically with nothing but RCS to propel them. This isn't a problem when only docking. However, this morning I had a mis-hap with a launch and had a part in a different orbit to the Station altogether. I did the normal autonomous rendezvous to Station. Everything worked fine, it activated and used the RCS thrusters instead of the liquid engines (as they had fallen back to Kerbin). However, MJ hadn't compensated for the low-thrust of the RCS engines and, hence, all the burns took way longer than expected, so the rendezvous failed. TL;DR? Can we please have MJ consider how long it would take to do a burn if only using RCS thrusters, so that it starts the burns early enough to be successful? Thanks in advance, and thanks for a fantastic mod. It makes my sciencing so much easier.
