Try this for the expander and arrow: do the tray with the cut out section in it. Then make the arrow image itself blank.
It's my fault if this is gonna be a pain in the ass, so I apologize now.
I'm not sure what you mean.
If you need images to show me, email me.
All my spare time is going into this and I have to get it done. I'll share credit with everyone who helps.
