Ideally, simple UI behaviour would handle many usage styles: small or maximized Explorer windows, single or multiple monitors, etc. Right-clicking any folder or file in SpaceSniffer opens the same menu that you see in File Explorer, meaning you can copy, delete, and perform other file functions.

The popups auto-size and position, but it's tricky.

Popup windows frequently cover up Explorer's Close button.

Background scanning is not optimized: Windows Vista/7/8 support I/O priorities, which should be used to keep scanning fast while keeping the system responsive.

This would work better with multiple accounts in Windows XP too. The service already does this internally. The system-permissions service should really be abandoned in favour of user-level caches.

The background service is difficult to manage with Windows's UAC model.

I've started this, but it's not working yet. This has the effect of making the Windows directory appear larger than it really is! I think the best solution is to split Size into two concepts: Logical Size and Physical size.

Sizes are difficult to interpret correctly! Since Windows Vista, the system makes use of hard links, where the same physical file can appear in multiple directory entries.
