Folder structure (exploration) — File panel folder structure exploration

An exploration of how folders could work in a file panel. I put three ideas on one page.

The first is a compact tree: arrows expand folders like Documents and Dev, and each row shows its owner. The second gives every folder its own card with the file count, when it was last edited and by whom, sorted by date added. The third is a search that finds nothing, answered with a small illustration and a suggestion to try different keywords.

Add file and New folder stay in the panel header throughout.
