By default, to a quote a portion of a thread, XF opens a drop-down with "Reply" option and it quotes that selected text in the quick reply box... This idea is based on similar lines... Add-on Context: Many a times, interesting and diverse thoughts shared in a post can become material for a entirely new discussion but are lost in a sea of other thoughts forever... This add-on can be especially useful tool for admins/mods or designated usergroups to initiate new threads from within the ongoing discussions by simply selecting the text / or a passage, automatically quoting the contents of the selection into the new thread. The selection drop-down menu can look something like the following image. Further, the new thread should also reference/link back to the connecting post or thread for the sake of continuity. Many Thanks.
