@aybe : yes unfortunately I saw it only after pushing everything and posting my message here. If I had known this before, i would probably not have spent time doing it.

- WOXL models : you can forget my changes and take phoboslab ones (they are very similar however). Phoboslab went one step further what we did, by adding some groups in the dropdown which make it easier to read.
- Camera : phoboslab fixed it by manually editing the ranges. the way i did it is by using track sections (this is more generic i think).

I send a mail to phoboslab about my camera fix (for review), maybe he will integrate it to his repository. we will see.
