Well, after using the dual composer feature on a few sites besides this one such as the one on Dillinger, Ghost, Discourse and a few other sites, I've come to the conclusion that the dual composer is a failure for the use of a forum for many reasons.
When you are composing something, you want as much space as possible to write. I feel squeezed and constrained in a sense because I have this window pane to the right of me taking up half the space to write on. I'm sure there are mixed feelings about this, but if I had to choose whether I wanted the double pane view or the single WYSIWYG editor, I would definitely choose WYSIWYG.
Use cases and many sites have successfully deployed this feature in unique ways keeping the logical approach as simple as possible. When you bold something you should be able to see it right then and there, and that goes for any type of formatting within the composer. I'm wondering what made you guys choose this over something more simplistic. There is completely no way possible this would work successfully for mobile (and I see why there is a mobile composer template created) and while the new mobile template for the composer can be useful in some ways, it ultimately was unnecessary.
Okay, so Discourse has it where you can hide the preview pane, okay cool - not. That still doesn't solve the problem here because you still can't see what you've formatted unless you reenable that pane again, so again its total bullshit.
When I think of a dual pane, I think of diff editors to compare edited changes, not for writing on a forum of any kind at all. Whoever originally thought this would be pretty neat for a forum should be banned for life of any form of UX that involves forums (and it doesn't originate here, so you guys are in the clear).
So was it the community or was it your own deduction as to what competitors/other sites have or was it because it was easier to implement because the preview pane is already there (basically a no brainer)?
In a UX standpoint its annoying to have so much wasted and unnecessary space just to see a live preview of your post when you can just see it using the WYSIWYG approach. I understand why the tabs were removed and the logic there was pretty flawed because I mean... who wants to click back and forth just to see if what you've typed is how you want it.

Yeah it's based on screen size. Right now the templates are identical... we're not actually sure if its a good idea to build two different composers, but it's there for now until we figure out what we're doing with it grinning
