The blinds might be the buyers. I always turn lights off and pull blinds to see just how dark a home is during the day because agents always light them up as much as possible so you don't notice which rooms are dark.

But the minor stuff moved is weird - unless someone bought a child then it's normal. Trying to stop a toddler touching stuff during inspections whilst getting a good look yourself can be a very tricky balancing act. The agent should put stuff back for you if it's moved but if they are focussed on talking up the house to a buyer that might be tricky.
