Don't know how feasible this is but anyway. In Space Rangers 2 you're able to right click on most info screens to pin that info to the bottom of the UI for future reference. This allowed you to easily compare trade good prices and keep track of news stories that were important like robots invading a nearby system. I think it would be useful if at least some of that functionality could be introduced into ES. Right now we already get notified at the beginning of a turn when things are built or research has completed and several other things. But what I'd like to see is the ability to pin a notification to the screen so that we could even more easily keep track of some things in the game. Say for example, the production queue of one of your main ship producing systems so each turn you could quickly hover over the notification and see if any of the ships in the queue can be bought or if there are ships in the hangar. Or say a fleet on its way to a distant system that you don't want to lose track of, the notification there could center on the fleet and display their stats (health, movement, etc.) when moused over.

I like this idea a lot.
