It would be well handy if research in progress would still show the tooltip for that research, rather than just “Stop researching this item” or whatever it is. Sure we know what they do, but sometimes I just want to check a certain aspect and have to stop it to check.
It might not work the way that this is implemented, and if not, they could always just also leave the research showing on the left panel and able to be hovered over, while it is researching. A good quality of life item IMO.
