Emacs: public test for my ‘dired-preview’ package
protesilaos.com
The ‘dired-preview’ package automatically displays the file at point in Emacs Dired buffers. This is the public testing phase.

From dired, preview different file types in a side window. The user can control the delay before previews appear, the maximum size of previewed files, and which file types should be excluded from preview.
