Multiline Field editor plugin question

Hi @pmario , Now for a specific project I am wanting to see the “split screen” (I think you call it split width?) open by default for the multiline field editor. I have a custom field and the text field, but I am finding that I have to click the split screen button for every tiddler. Normally that would be my process, but for this project I would like them both to appear side by side without having to click the button. I looked through the wikilab settings but I don’t see it.
