I have added hvacengi's new GUI program into a version 1.23 easy edition (in first post).

It works great, and i can toggle types between native hildon apps and dbus-switchboard now... so for mp3, i can intercept for xmms or disable default for normal Media Player... without rebooting.

So no longer need to edit any files.

You may need to reboot after install... if the menu link doesn't start the program, then reboot.

If you use personal-menu or personal-launcher, you will need to delete and re-add the shortcut since startup has changed.

Thanks hvacengi for all your work on making this GUI simple enough for casual use and users. It will allow me to try many more combinations of file types and handlers now.
