Just little details that dont change the game just make it IMHO a bit easier to play.
Trading; you have to click very many times to exchange 150 tech for res, adding a slider would be nice.
In the Personnel Health is Green and Stamina light blue (cyan aqua dont know how to call it) in Geoscape health is light blue and stamina white. Use the same color coding for both
In personell, when you have two populated bases, and you want to decide the team that will go on the Manticore would be nice to have a filter not to see soldiers in the other bases
When deploying the squad, just before the mission, and check the equipment; again be able to filter off soldiers not in the Manticore
In tactical, on the left there are symbols showing level, training and AP of the soldiers; add the health.
In Bases it marks second base you get as number 1 and starting one as 2; number them in the order we get them. I never had more than two but i guess that when you advance in the game and have half a dozen being able to rename them like: North Africa, Pakistan, Japan, Alaska could be useful.
