A previews button on the Files tab turns the icon column into a 256 px thumbnail for every image and video row, loaded as rows scroll near. internal/thumbs probes what the machine can do rather than assuming it: ffmpeg and ffprobe, every /dev/dri/renderD* opened and exercised, vainfo's decode profiles per node where it exists. A video goes to the first GPU that lists its codec, with ffmpeg's own software fallback behind it and a CPU retry behind that; images decode on the CPU, JPEGs at a reduced DCT size. Previews are kept under <data dir>/thumbs/ keyed by path, size and mtime, with undecodable files remembered too. Root mode makes them through the same root helper the file reads use. Where ffmpeg is missing the tab offers to install it; where a render node exists but is closed to the daemon's user, it offers a drop-in adding the group and a restart.
