Previously, it was possible to collapse or expand multiple layer groups simultaneously, but it no longer seems possible. It was as simple as selecting multiple groups and holding the CMD key while clicking on one if their chevron icon-button.
This ability seems to have been removed, unless it’s simply the shortcut that changed?
This feature was quite useful to navigate quickly within the layers panel. It would be great to bring it back as it doesn’t seem to conflict with any new features.
