Inventory / Skills screen space usage

Around 50% of screen space is unused.

I like the headers orbs, and live action in the center, these should remain as the default setting.

Add a maximize button to expand the left/right and panels to fully use each half of the screen. This will be very effective when doing inventory stuff.

On my screen, the quad tabs are too small. Expanding the quads size will make them easier to see, and easier to place items without overlapping.

For Gems Tab and maybe others, expanding will show more on-screen, less need to scroll and filter.

Skills when all expanded should all show without scrolling.
