Right now, there seems to be these three layouts for a character sheet: Mobile, Tablet, and Narrow Monitor. 

My issue is that I have a widescreen monitor and would like to see my character across it. When I go full screen,  it looks like this:

As you can see, there is a ton of wasted space on the screen, and still a ton of tabs to click through. 

Could we not have something like this as an option when in fullscreen?

Thanks for reading, and thanks for your consideration!

I would also like to have this as an option 

I like this! And would also like better full screen layout options for character sheets. 

One thing I've noticed about going into Fullscreen on a 1080p Monitor is there's a slight bit of scroll space of about 12 pixels at 100% zoom, making using the scroll wheel a little awkward.

I would super love this too, i hate that the meat of the character (all of this https://i.imgur.com/PTWOYZB.png) is about a fourth of my screen.

all those tabs have subtabs too. Even if all my ability scores, skills, saves, proficiencies, health, and armor class were all to the left and they just made that window like half my screen it'd be way better

Addendum: Vertical screen support

This is on a vertical 9:16 monitor - but the character sheet will not go any further down then it would on a 16:9 screen. 

Who do we need to know to get traction on this? Is there a ticket submission area for improvements?

Even just letting everything shift to the left when the extra pane is open would make a HUGE difference.
