Hello to everybody, I have been searching for this topic in the forum, and surprisingly there is not a lot about it (at least for my serach capabilities).    Would be useful if layer naming would behave as class naming (the dash make a hierarchical organization).   Is there a reason why this is not possible? I have found many suggestions on how to achieve a similar result, tags, filters, but no one looks to me as simpe as just turning on an off a group of three or four layers
