I suggested that here: http://xenforo.com/community/threads/suggestion-allow-custom-bbcode.1513/(and a way for making new BBCodes).
This has already been suggested here -Noticed there is no quote button in the editor, I often copy text in to posts, highlight it then hit the quote button.
Nice as mod, but no way that it can serve as a core feature. Just too hard to discover/obscure for new members.I would not miss quote button if we had something like "iquote" mod for vB.
When you select text with mouse, you'll see a popup quote button which you can press and then it will automatically add quoted text to the reply, it can be used as multi quote as well. This is brilliant.
I am using this feature on my vB forum and my users absolutely love it.
This mod for vB can be found here: http://www.vbulletin.org/forum/showthread.php?t=248504
