So when player has 130 units selected, then he would have 3 tabs - 60, 60 and 10 units. Here player has selected unit thumbnails grouped into 3 tabs, between which he can switch.Įasiest way to switch between tabs would be by making them scrollable by mouse wheel when cursor is hovering in section of selected unit thumbnails. Might solve it how Starcraft 2 has done it - with tabs. Main problem is how to fit very many selected unit thumbnails into UI. Developer Neros tested selection limit of 200 during beta and found, that it caused no noticeable performance impact, so there are no reasons to worry about performance.
