/* TODO:
* - implement "always ask" for the default download directory
* - draw the progress bar inside the location bar
* - provide access to SSL information in embedded mode
* - rework preferences handling:
* * no longer cache settings outside of Config *
* * use helpers to draw widgets and load/save/set preferences
* - support separate backends via plug-ins (with own preferences)
* - consider putting the location bar below the tabs
* - consider using GtkSourceView to display the page source
* - consider moving the find dialog above the status bar */
