(XDG-URL) A few suggestions

First off all thanks for this great program. It works quite nicely, but I have a few suggestions.

  1. It seems that xdgurl is using (Tk GUI toolkit) for its interface. Please consider making it look more native by using zenity or qdialog. I understand that XDG-URL may require a few more dependencies hence my second suggestion.
  2. Provide xdgurl as an AppImage http://appimage.org/. This way you can support most of the Linux distros and bundle all dependencies into appimage, so the user will not have to install anything.
  3. Show progress bar while downloading files. Useful when one downloads bigger files like icons.
