so it would be nice if there was a create variable block with a text field for the variable name it would make making sprites on demand a lot easier. also if the variable part of a set variable to block could be replaced with a function variable that would be nice.

You can use arrays.  
Just append and pop values/strings/sprites from the array in the advanced catagory
