fn batch_strip(ui: &mut Ui, state: &LibraryState, resp: &mut LibraryResponse)Expand description
What to do with everything selected. Every button routes through the LibraryResponse fields the
per-item menus already use, so App needs no new plumbing.
ponytail: the Convert and Compress windows each take one file, so those two open on the first asset
of the selection. Upgrade: queue one job per asset once those windows accept a list.
