resolver ui feature request

Hi there,

Here's a little feature request, let me know what you think about it.

This is how the URL input together with the resolver works today:

The user inputs the URL inside the entry-widget and tells the browser
that it wants to load the page by pressing enter. If the browser is
unable to resolve the page a popup is used to notify the user.

This is another way to do it:

The user inputs the URL inside the entry-widget and the browser starts
resolving directly after the hostname-part of the URL has been entered.
If the browser is unable to resolve the page the hostname-part of the 
URL is underlined (PANGO_UNDERLINE_ERROR). The page will not be loaded
until URL is free of underlines. And optionally you can have a popup.

Thanks!
