The search feature current available within the platform is very limited as it only allows you to search within the top-level of the "folder" hierarchy, within any of the given areas of the system (Lists, Tables, etc.).
The feature should ideally search through all folders starting with the currently selected folder in the hierarchy, traversing down through all child sub-folders.
Without this capability, the search feature is relatively ineffective for anyone utilizing the Folder system for object organization.
If this could also be implemented in the content section as well that'd be great. We have a lot of content and a way to quickly find a piece of content and its location would be great (similar to how you can quickly search for content in the "Send Email" action in workflows.)
