Multiple tab rows (tested with 3 tab rows) cause a scroll bar to appear. This bar causes the tabs to scroll up by one. If a tab displays multiple maps both scroll bars will be displayed.
Don't know if this is still being updated, but I wanted to say, I've started using the mod recently on my new pc and my custom systems wouldn't show up at all the on the "My Systems" tab. Every other tab from map packs would work just fine, all systems and categories there except for my own. Today I tried disabling the mod and all my custom systems were there now, in the general list. Are there any know mod conflicts that would result in this bug? Or should I try applying the proccess of elimination for each mod I have? Pic is how "My Systems" tab looks with the mod on.
