The following behavior should probably be changed:
Let's say you have BGT Mk 15:34 open. You then open the Synoptic parallels window and copy something from John. then you close this Synoptics window and want to open Robertson's Wordpictures. It opens in John and not in Mark as expected since it's the open verse.
Similarly if you want to open verse 15:44 then, by typing simply "44", you cannot do that because BW "thinks" it is in John.
