movement lag is better for some units, but it's worse for Army Commanders, and for the first commander on my list there's a significant lag just from clicking on the unit. the panel itself feels sluggish and is slow to open. there's also a conflict with the Border Toggles mod that prevents me from using the pull-tab option.
besides the lag, i've been frustrated by conflicts between the UM panel and other interface elements. the top of the panel partly overlaps the yield bar, and the minimap is visible through the bottom which makes the text difficult to read. consider hiding the minimap while the panel is open – see how Detailed Map Tacks handles this. speaking of DMT, i also prefer its open/close mechanism, which uses a single button and recognizes the right-click close shortcut.
this mod does some things really well, and i've been excited to try each new version. unfortunately, i've had to disable it again pretty quickly after each update because of usability problems and conflicts with other mods that i rely on.
