Without(!) addon modules for load in SE. Addon coming soon.

"5" or "S" - rotation modules
"4" "6" or "A" "D" - move modules on Z
"<" ">" - move ship on Z
new modules of concept
Hmm.. does this mean spacecrafts build with this version won't show up in SE? I just made a ''test.sss'' with the emergency live habitat module only and it doesn't show in-game

Otherwise it looks very good!
A few more questions:
Do you know if and how we can role main engine so that it faces 180
o opposite -I tried "5" and "S" while holding down various buttons + mouse keys in any possible combination but it doesn't seem to do the trick _ I am probably missing something there. I don't want to use double sided engine - don't want to burn the habitat during accel phase lol.
And finally the 3 axis RCS desn't seem to produce a plum effect in-game. The old RCS without forward-backward engine bell produces the nice blue plum effect..
