Adding speed select to GUI

Could be more elegant, but appears to work
Hi Dan, it looks like the change is not against the latest version, the version put on github was newer than the one I provided you. Things like this formatting, and other changes and cleanup I've done would be lost if this is merged. Can you update your change so it's not lost. Now that it is on github, issues like this should not happen, we should easily be able to merge and rebase our changes with minimal manual changes.
