Potential Pullquotes Plugin.
Pull quotes - you surround your text with pullquote tags and it pulls a copy of text over to right and highlights.
I modified my button bar to have the Pullquote button that adds pullquote tags around selected text.
But you could still add your own [pullquote] tags manually.
I'll upload it if anyone wants to try to outfox (fix) a few css issues. Anyone interested in messing with css for a potential plugin.
As you can see it is on the right hand side. It needs a bit of work. Still got a few css problems. Any one try to fix, if I upload it.
had to add extra lines here, otherwise pullquote overflows message box.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
