In the managing soldiers menu, when you click a soldier in the reserve, the soldiers of that class are highlighted (assuming you have the role filled).
When trying to switch in unleveled soldiers in the reserve to train them, I often find myself squinting and leaning close to my monitor trying to find the hollow stars of a specific class which I have found annoying for ages now.
I propose that when you select an active soldier that it highlights all soldiers of that class that are in the reserve. This would alleviate the minor discomfort and improve the user experience of managing soldiers in the menu to level them up.
This has bothered me for ages and since I’m on the forums, I figured I would propose this UX/UI improvement.
