The 3d rendering of system objects has nothing to do with the interface, which is still essentially static 2d (and can be entirely customized via bitmaps, unlike se4). I'm not sure if the Data\HUDSettings.txt file actually works, but it might be possible to create a more-sane button panel with it. AFAIK the button panel and some excessive confirmation dialogs (for general "clickiness") are the main issues left with the interface, other than possibly the ship design screen that we are stuck with. There are little things that could be done like double clicking on a sector with a planet automatically selecting (the first) planet in that sector, but those tend to be not unique to SE5 (could improve SE4 as well). The interface has come a long way since release.
