Remember previously used URLs on login screen

The url on the login screen is often long and complicated. It would be good to have the app remember the urls that have been entered correctly and have a way to clear the list.
If the url is remembered, then the user can select it from a drop down list if there is one or more. If there is only one remembered then have that one auto filled into the url field (if the setting to remember login details is set in the app settings).
