This would be fantastic. I can see the macros getting quite sophisticated.

This would be especially cool if, for unmanned probes, commands couldn't be given in real time, but were delayed based on distance from nearest manned spacecraft.

Perhaps embed a lightweight scripting language like http://www.squirrel-lang.org/ or Lua?

This would make flying rockets sooooo much easier

If there was a computer module that you had to add on to have autopilot would make it way less over powered. launching a satellite would be faster, a press play and wait for control of the satellite

Also manual override would be required in emergency situations

Sometimes having an encounter with another planet can be difficult so i suggest you to put a trajectory editor, i know it's not easy for you but it would help the game so much.
Also i suggest you to create other solar systems that we can reach by interplanetary travel and a faster time warp.

make sure it is available for android please

add a truss that can extend and contract and auto pilot for docking

pseudo-code example

;Simple Rockets Macro - filename: experiment1.srm
;This is a simple macro to launch a rocket and deploy a parachute

Load rocket29a ;if Load is not present, just attempt
; to run the macro on current rocket

Rotate -30 ;30 degrees counter-clockwise

Countdown 10 ;display countdown from 10 to 0

Throttle 100

Stage ;same as pushing Stage button

Wait Fuel 0 ;wait at this point until fuell is out

Throttle 0

Stage ;detacher

Wait Altitude 300

Stage ;parachute

Wait Velocity 0

Wait Time 3000 ;wait 30 seconds after it lands

Destroy

This would be awesome. Fully automated ships. (autopilot)

I'd like to have the ability to program the rocket to automatically activate a stage when a criteria is matched (and the stage is armed). Like, activate an engine, turn the rocket, upon reaching a height. This might not be a thing for some people, but it allows more precision, and it's also how it's done in real life.

You can set it like,your orbiting the sun so you can program it to stop warping 10 seconds before apoapsis or close approach

Add Auto pilot that creates approch to planets for you. For example to get you into smoons SOI for non advanced users and leisure play

I like this!
Bump!

Alternatively to time (fly for 20 seconds) use altitudes (At 15000m turn +35 degrees)

the ability to switch on a predicted track with a setting for the vector and time boosted, so for example you give it a direction, velocity and a number of seconds and it plots a dotted line to show you where that maneuver would end up... the option to use this in pause mode would make it more effective
