The align tool always selects a whole layer group, picking individual layers from a group is impossible
Submitted by FernandoBasso
When there are several layers inside a layer group, trying to click on one of the layers in the canvas (not in the layers panel), always selects the topmost layer.
I noticed this problem when trying to use the Align Tool to align a certain layer to another layer, both of which were inside a layer group.
Tested gimp 2.8.16 on xubuntu and gimp 2.8.18 on arch linux.
Some other people talked about this situation already as well:
