Hehe, I also hope you're not complaining.
So here is 3DEditor 14.7.
What he affords is what seems a fine .bin file support through sliced tarmac .gp4 shape. It also brings new coloured icons to quickly identify format types and also now open as it should big .gp4 objects making them visible.
And obviously it fixes as many bugs as I noticed.
so here is the history log:
v14.7 (july 13th 2005)
New: Sliced tarmac when converting .dat to .3ds
New: Color scheme for associated files icons
Enhanced: Double-clicking in the track flag list now leads to the command line
Enhanced: non original .gp4 files are now visible whatever the objects sizes
Fixed: Prevent from removing first essential sectors
Fixed: Point of view was reseted to origin when loading some .gp4 files
Fixed: Texture 2D preview was disabled if a .cam file was loaded
Fixed: Small track pitch computation error with final pitlane sector
Fixed: old kerbs were not always deleted when creating new kerbs
Fixed: Enabled GP4 sector limit warning
And the preview:
