v0.6.1

• The media library's filter row now leads with the file count of the open folder. The grid loads more tiles as the user scrolls, so the number of tiles never answered "how much is in here".
• A file without a displayable preview no longer falls back to one generic grey document. Noerd\Media\Support\FileTypeIcon maps the extension to a heroicon and a colour: PDF red, Word blue, spreadsheets green, presentations orange, archives amber, media purple, everything unknown grey. Where Ghostscript is installed a PDF still shows its real page preview.
