is there a trick to organize a small kitchen?

Go up, not out. Shelf risers inside the cupboards double the space for mugs and tins, hooks under the wall units take the mugs off the shelf altogether, and the inside of the cupboard doors will hold lids or a slim rack for foil and wraps. But do the boring part first - pull out every duplicate. Most small kitchens are carrying three sieves and two of everything, and that's the space you're short of. Keep the worktop for the kettle and whatever you use daily, nothing else.
