Yes. You gain nothing in terms of size of image which for me is only
reason to change (OK, not only - more below). Space occupied by
horizontal panel takes whole black strips height. This is only question
of aesthetics. Nothing is gained.

No. In such situation portraits are losers. You gain nothing for
horizontal images and lost much for portraits. Overall result is loss.

The only gain would be possibility to have *two* open panels, one
vertical and one horizontal.

Small computation:

in 1024x768 image with full size of 2048x1365 with open panel has 575x380

Panels' tabs       20px
Panel             340
Image             575
Photostrip+scroll  90
                 ------
		 1025px <- small rounding :)
Decoration:       450px

Now, judging from design of panels it would require major design of
widgets panels cannot be smaller than 220px in height. So we have
elements of GUI

Kicker[1]          30px
Title bar          25
Menu bar           20
Tool bar           35
Status bar         20
Panels' tabs       20
Panel             220
                -------
		  370px

		  768-370=398px

In result image can be 585x398. Really tiny improvement. And check
effects for portraits instead of ca. 700px they have only half of that.

[1] I have small Kicker, By default it is bigger - even worse for image.

You have to do your own math.
