Adguard needs to have an option where the user can save ALL settings to a file, and then restore ALL settings from the file. Some of the stuff that needs to be saved and restored are: - All the settings and the way those settings are configured exactly. - Any filters the user. This should be ALL filters, be it user filters, or any other types. - The say the filter is currently configured. This means that, for example, any rules disabled within filters should be saved and resorted the exact way. - Any license file information. This way, a user can set up Adguard once, and know that they can safely back up everything and restore in a matter of seconds after installing on a clean PC or after a system reformat. AdMuncher had a very good save and restore system. It even let you select what to save/restore.
