Better repl icon for "Cancel Execution"
Just a suggestion that one of the icons from the second row of the attached file (taken from the VS2010 image library) may provide a clearer distinction between the Cancel Execution button and the Clear Screen button.
(Mainly suggesting this because I've had to wait for the tooltip three times in the last five minutes because I can't tell them apart easily enough by the image. I assume I'm not an outlier here, though it's possible...)
I'm happy to put together some "nice" icons here if this is too low a priority.
