I think, this is not possible, because there are much things to do (see Errors and Wishes).
It has probably nothing to do with this Thread. Since the option won´t be implemented soon enough.
This option is more than just onced wished, probably everyone could have a use for it.
But its Woltlabs decision.
There are so many things that have been made in 4.1 and will be still comming and they probably need such a ton of work to do so.
And I never and many others won´t use that features, maybe 5-10%.
But that Feature in this Thread can wait...
Probably just Tweaks in CSS and a few PHP Lines to see if the Thread is yours.
But I am not a wfc coder, sadly
