The UI right now generates, for each planet completing a job, a message icon - it can get REALLY tedious to move the mouse back and forth click on the icons. Surely, you can scroll "previous" or "next" planet - what would be a better is only 1 job icon is displayed. An overview UI screen comes up when that icon is clicked.
On this overview UI screen, it will display 1) a list of planets completing a job last term, 2) the job (project) completed, 3) the next queued job (or nothing queued). Space-permitting, maybe effect or other useful/relevant info.
The same idea applies to icons about spaceship construction completion. Or perhaps, the overview UI screen has tabs - job/project tab vs shipbuilding tab vs.... Having a player moving mouse across the screen several times a turn just to click on those icons isn't very user-friendly...
