When I have multiple SQL statements in the SQL window and I do CTRL+ENTER (or press the button), only the current SQL statement is executed.
To execute all SQL statements in my window, I have to mark all (so cursor jumps at bottom) and then CTRL+ENTER.
To continue modifing my SQL, I have then to sroll up until I'm on the line to work on.
Maybe I missed it in 3.5.0, but why not having a second button and shortcut (e.g. CTRL+SHIFT+ENTER, or better configurable) which executes complete SQL window statements from top to bottom, and leaves cursor where it is ...
