Fullscreen and Menu Bar

Haven't posted on the boards in awhile. Anyway...

So before I describe my issue I want to say I know how to solve each one separately but I don't want to choose between on or the other if possible.

So here it is lol: I have dual monitors. I don't like having the menu bar/dock on both monitors it can be very annoying especially dock if I'm working in a large window. I want those ONLY on primary display.

When I put an app in fullscreen mode I don't want my other screen blacked out. I could work around it in order to have one instance of menu bar and dock but occasionally I want say a youtube video to play fullscreen while I continue working.

Is there a way to achieve this? Even if it involves 3rd party software?

Thanks in advance guys! This forum never ceases to amaze me
