Two things that I've seen a lot in the videos, that may be easy to change..
It may lessen the grief of some players. (Some even needed to take a rage time-out in video

)
1. Colonists do often stop their work because they want to do something else.
This seems to annoy most players. Especially when they are building something big and needed at this moment, like a turret before an pirate attack. The colonist sometimes just leaves the work half finished to do something else.
I think the test, if they should do something else, should only be performed after a task is finished, not while it is running. So they would build the dispenser / turret until it's finished and get their food a bit later..
At least it should be changed for prioritised work items.
2. It should be possible to give drafted colonists the order to repair something like a damaged turret, so that they don't run of afterwards.
Right now the players undraft them, let them repair, and when they don't watch out, the repair man runs of to do something else somewhere far away from the battle. Or even better he runs towards the pirates..

I'm not sure if it was already mentioned or not...
