Hi michaelc
Thanks for your suggestion. I found that removing it totally from the ftl caused more problems than it solved. So I went into web-preview.js and commented out the line "so.write(this.widgets.realSwfDivEl.get("id"));", this stops the previewer from loading.
Then I modified the CSS so that real estate of the screen isn't being taken up quite so much, then modified some properties of web-preview so that the text fits with the new context of not having a previewer.
I know you can remove the previewer by using share-config, but it still loads up space for the previewer so it doesn't "totally" remove it.
Thanks for your help!
