An idea to fix a broken tile area. Don't tear out the wall of tile, make light of it! Caulk the broken/missing tile to waterproof, then add an air fern (kitchen backsplash) or a fake plant (shower or tub area).
Minifigure storage -get a glass picture frame. put the color of paper you want inside the frame. super glue the bricks to the glass and snap your figures into the bricks! my future kids will play with legos. lots of legos.
