A Few Ideas

I got to thinking and the following popped into my head. My first suggestion would be to let the poster set what the material will be going between. At the moment I’m thinking of the div and /div tags. The multicolumn CSS would then go between them. A button on the visual editor for adding the div tag, then the /div tag. I know you’d really have to use the text editor for the tags, but there maybe someway to do it using the visual.
