When opening up a project and intereacting with the "Open 
Project" dialog there are two buttons at the bottom that are 
confusing enought that I always mess up.  They are the "Open" 
and "Open Project Folder" buttons.  When I first encountered 
them I thought that "Open" meant "open the project" and "Open 
Project Folder" meant "look inside the folder to see if there are 
things inside".  This (wrong) assumption was bolstered by the 
fact that "Open" was the default button, which corresponded to 
my intuition about which was the most likely action for me to 
want to perform.  But, in fact, the meanings are reversed.  Both 
the button labels and the default action are totally the opposite 
of what I had expected.  I suggest relabeling the buttons to 
something like "Open Project" and "Open Folder", and making 
"Open Project" be the default.
