Custom Form Floating Modal

The current layout when when filling out custom form request could use a UI update. As seen in the attached image there is a lot of unused space when filling out a new request in Workfront. The new request page could easily be a floating page/modal that would allow users to still view the background information. This "Post an Idea" form actually models what I think would be a better layout for the "New Request" form. I took a screen shot of this floating modal as an example to compare to the current slide tab in "New Requests".

If you like the idea please feel free to like and let's watch this grow!
