I'd like to suggest a feature regarding the Layout Tool: EITHER have it open in a separate tab, OR add a Preflight button within the interface
I understand why you have now defaulted to have it open the last collection upon launch. It becomes tedious, when testing your layout on a device, to constantly switch back and forth from the Content area of the tool, to the Layout Template, and having to reload your collection each time you push an preflight update to your device.
When I'm ready to be viewing (especially with embedded fonts) on a device, I typically work w/ 2 browser tabs open: one for Content, one for Layout Template. That way, I can save content within the Layout Template, quickly switch to the next tab, and Preflight the content.
Seems like it would make much more sense to simply add a Preflight button within the Layout Template screen.
Thanks for listening!
