Create group layers

#1

Hi,
As we can’t make symbology by value field, I make several layers (one for each field value). It makes a lot of layers (wich are displaying on screen so fast, that’s amazing, thank you).
For ergonomic reasons, it will be so cool to be able to make group layers (we can only display the group on tyhe list of layers and on the map).
Do you think that it’s possible?
Thanks for your answer.
