To get rid of tonnage bar(move it out of view) you must only change the lines under progress frame in
data/Menu/Pages/Page navigation map.ini. For instance like this:
Name=ProgressFrame
Type=1030;Static bmp
ItemID=0x31110002
ParentID=0x31110000
Pos=15000,-74,0,1
Zone= 15312 824 0 1 0 1 0x31110001 100 -1.5 0x31110002 0 1 0 0
Materials=1
Display=2;Linear
Mat 0=data/menu/gui/strategicmapnew.dds
Crop 0=0.625,0.365234,0.294922,0.0078125
MatFlags=0x9
TexFmt=0x0
I found this mod, I've done a while ago for myself. It changes IO map layout back to vannila. TWOS IO map is nice, but for my eyes default map is better. If nothing else, you'll see what files are associated with nav map. Use this with no-tonnage campaigns, but you can test it with vanilla game. It's JSGME ready.
