The separation of layers into groups is great.
You need to add an option to filter the entire group, because when you have a group with 15 layers, you have to select them one by one in the filtering.
I understand that I can create and save presets, but selecting all layers in the group would be very helpful in various quick situations.
Actually you don't need to select them one by one. You can click on the first and then Shift+click on the last to select a range of layers (across groups too!). If you just want to select all layers in a group you can Alt/Option+click on any of the layers in the group to quickly select all layers in a group.
option+click on the last with mac OS.
Will maybe more efficient if just need to click option+title of the group instead of scrolling until the botom of the group...?
