I want to build a self-hosted, open-source cloud storage system—kind of like a private Dropbox or Google Drive. It should let users sync files and folders from their desktops into collections called 'libraries.' For privacy, users must be able to encrypt individual libraries with a password. It needs strong collaboration features: sharing folders with other users or into groups, creating password-protected download links, and even public upload links for collecting files.

Beyond just file storage, it should double as a knowledge management hub. Include a web interface with a nice WYSIWYG Markdown editor for documents, a built-in wiki mode, and a way to add file labels. The desktop client should have a virtual drive feature so users can access all their cloud files on-demand without syncing them all at once. Basically, create a complete system with a server, a web UI, and desktop clients.
