Nice GUI utility for tidy; could use some minor tweaks

This is a GUI app wrapping the classic tidy utility, very helpful if you’d like to bypass fiddling with command line issues for quick experimentation. A drawback that will hinder some is that it appears to enforce an html file extension, so won’t open xml or other files. It would be useful to have the ability to hide the options and messages panes to maximize screen real estate for input/output review. Also, it would benefit keyboard-centric users to have keyboard shortcuts to set options, eg the pane show/hide functionality, toggling tidy settings, etc. Other than these minor issues, it’s a worthy repackaging of the great tidy functionality.
