Feature Request + Bug: Preview of Gallery image doesn't work

Bulk editing no longer works

Two reason: Performance: Computing an aggregate view for the inspector for all selected listings can take some time, especially for users with low-end machines. We didn’t want to make users wait everytime they click on on a group with several thousand items. Consistency: In theory we could change this behaviour if only a few items are bulk-selected, but then the behaviour would be inconstent.
