This weekend as I was beating on 0.21, I noticed something that was rather visually disruptive and in an area that I'm not expecting to get a total overhaul soon (which is why I'm not commenting on the tech screen).
If you colonize a decent sized planet, then queue up something to be built in most of the zones, then remember that you need a starport asap, place the starport, then use the up button to move it earlier in the queue, the queue scrolls to the top, even if this hides the item you're moving. The first time it did this, I thought a bug had caused the first item in the queue to get selected, since the curently -iunder-construction item gets displayed differently. Not a major bug, and one that might have been brought up before, though if it has, I don't remember it and can't see it listed.
