Collapsed group suggestion (feature request)

To have an option 'click on horizontal group bar to expand/collapse group'
which when enabled would change the current expand/collapse glyphs to select all in group checkboxes please.

You can select all files in the group by clicking the group header.

Yes I know that, what i wanted was to be able click the group header to expand/collapse the group :grinning:

This program is fantastic, ignore post, just discovered double clicking on the header does the same job :grinning:
