This is a VERY SMALL addition to XenForo I would like to see made and it's quite easy to do this in the templates. But for those users who don't like to play around in templates this might be helpful.
In Basic Forum Options, I would like to see a new field for the Forum Home Title. This would essentially be a specific title for the main landing page of the forum installation. So if your Board Title (Name) is "My Forum" and your Forum Home Title is "My Forum - The Premier Forum for Everyone and Everything", you can set that. Good for adding a description of what your forum does and on every other page it still has the simple "Random Page Title | My Forum".
Does that make sense? Hope it does .
