Thumbnail settings

Catwalk renders the selected file types. By default, it is enabled for types without a built-in Manyfold thumbnail provider.

Catwalk is downloaded from GitHub when an enabled file first needs a thumbnail, then reused from the local cache.

Catwalk is not overriding any built-in thumbnail providers.

Extensions on the same row use the same provider and are enabled together. Enable Catwalk to replace the built-in provider; disabling it restores that provider where available.

Changes apply to future thumbnails and manual regeneration. Existing thumbnails are retained.
