The Swipe widget is confusing and unpractical to use with grouped layers.
-Names of layers and groups are listed in the widget undifferently, without hierarchy.
-Checked layers from non visible groups (in the Layer widget) will appear as activated, with a blue tickbox in the Swipe widget. But those layers are not visible in the map. Checking/unchecking those layers in the Swipe widget has no effect, which is confusing for a user.
-Similary, Toggle layer visibility in the widget is not usable as is has no effect on layers from a group layer that is turned off in the Layer widget.
Suggestion: the group/subgroup/layer hierarchical structure from the Layer widget should be kept in the Swipe widget.
In addition it would be more intuitive and more using friendly without the grey tickboxes/without having to interact with two different widgets (Layer and Swipe) in parallel. The Swipe widget would display 2 lists with the hierarchical layer structure, without the grey tickboxes. The user can simply choose which leading and trailing layers should be visible. The two lists could be side by side when using vertical swipe line. Even better, it could be only one list where each layer/group has 2 tickboxes, one for the leading layers, the second one for the trailing layers.
