Logical organization of files or file tags / labels for easy access

When I have more than 10 pages of files associated to a project the file area becomes difficult manage and almost impossible to find items. 

I have a couple of suggestions. 

• File Tags
  • if we could color code and tag files with keywords similar to features it might make it easier to find items or associate files to tags which are related to the feature the file is associated too. 
• Caption column in the file list view
• Searchable Captions 
• Searchable Tags
• Logical folder organization or labeling
