I would love to - - be able to open a "Solution Guide" while still being able to see and work in the Solution. It would be helpful to view the reference material while working on the project or task it refers to.

Maybe the "Solution Guide" could open in a floating window? (may be annoying or still get in the way, though)

Perhaps it could open in a sidebar?

Or perhaps the ability to open in a new tab / new window?

I'm sure there are multiple ways to achieve this, but I don't know how much development work is required for any of them.

Got my workaround for now ... It's just clunky :D
