Hi,

One thing not in the v3 (but in the v2) is the ability to assign a layer to an entity by double click on the layer name (in the layers list)

On V 2 :
1 - Select entity
2 - Double click on the layer's name

> then le entity is in this layer

On V 3 :
1 - Select entity
2 - Double click on the layer's name

> nothing change

It's useful to change it by this way, please make it possible in v3.
