[chpicone]

The customer is asking for:

• reduce the width of the TOC (Table Of Content). I suggested him to reduce to the 75% of the original size.
• adjust the size of the layer widget accorindg to the TOC container and having always 2 columns. In the image below we can see the 2 layers are not in the same row!
