when grouping layers in a custom map, the layer name is not kept, but replaced by "layer" followed by the order number:
layer #1
layer #2
...
which is not very convenient for users!
Create a custom map, with 3 or 4 maps
Display a map using this custom map
See screenshots
use map name instead of t('layer') . " #$i"; in switcher key.
