It'd nice to be able to click an icon or button in the home view to access my 'favourite searches', be it 'all photos with missing location tag', 'photos of my family' or 'tokens, K, J or L AND me on it'.

This way I'd get a straight access to any photo set I want.

Of course it's possible to create a category for my custom sets - but they aren't updated dynamically which makes it a pain to remember to not only tag all photos (people etc..) - but also to remember to add them to sets.
