Hope I'm not spamming or anything. There were a few features suggestions in MechJeb which I've thought would be relatively easy to integrate and also somewhat helpful.

1. true vertical acceleration:
   essentially the local gravity minus the vertical component of acceleration due to thrust.
   This would be helpful for manual fly-by-wire landings while avoiding the whole "crap we're too close/max thrust" situation. (Also for ascent with vulnerable payloads)

2. limit true vertical acceleration:
   same as above but the ability to increase or decrease the thrust automatically for the same reasons during ascent or landing.

3. maximize sun exposure: (well sorta)
   the idea is that this would be an easy way to aim the craft to maximize solar panel output. usually i just select the sun and do +target on the A.S.S but the panels aren't always radially attached in a ring... idealy, if you just had one panel this would be able to automatically detect the right angle for it... idk might be too hard to implement

4. aerobraking tuner:
   just taking that "orbit after aerobraking" thingy out of the lading thing and adding it to the manuvermaker with the ability to tune the apoapsis of the desired orbit instead

5)auto deorbit w/RCS:
an automatic feature which uses fires its engines and linear RCS so it is poshed retrograde and then stops when the orbit does not re-enter

6)distance from SOI
self explanatory, more of a "soi altitud - current altitude" sorta thing

fantastic work as usual
