Hi Alex, yes the UI structure is slightly different from V3 to V4, which means that you can't just copy the V3 version of SidePane.htm into V4. Instead you need to edit the V4 file. But the structure is similar enough that using the same directions described above for how to edit the V3 file (http://moi3d.com/forum/index.php?webtag=MOI&msg=8064.2) will also work for V4.
