New files section

I'm about to start working on new project files section. Current documents section is pretty limited and not so useful. Here are some notes:

• Files in folders. There will be no folder hierarchy in first version
• Files can be sorted by upload time or by name
• Thumbnails for supported types
• Searchable file types (text documents for instance). In that case script will add their content to search index (indexing can be restricted by type and by file size)
• File versioning. Files can be checked out (locked until user who checked it out does not check it in)
• Users can comment on files
• Default set of folders that are created when project is created. This set can be changed from administration

This one is one of the biggest changes planed for 1.0. It will also introduce attach file to anything and comment on anything features. It should will be fun ;)
