Since Bini isn't playing VG anymore, and there must be more ManicUIholics like me I decided to take a crack at making this work with Fishing.
Take a backup of the following files in the <Vanguard Base>\VGUIAssets\Shells\ManicUI\Windows Directory.
Manic-Character.xml
Manic-Quests.xml
Replace those with these and relaunch your client. I wish I could make a user friendly installation but unfortunately time doesn't permit me. Good luck and hope this works for you.
