We can ALL view whatever width aquarium our screen, (or number of screens), will allow. - And we have the option to pan or not pan, and display which ever section we choose if we decide to lock the panning.
As I have said elsewhere....
I think that we should accept that MA3 is a
VERY wide tank, and if we want to see the whole of it on one screen, then we
have to have a very much reduced-height window. - If a version with black at the top and bottom, (a la MA2.6), becomes available, then fine for those who do not like making the necessary shape window. - But to distort the image in any way, in order to fit the full height of a single screen, is ridiculous IMO.
I quite like seeing the population change slightly as some fish swim off screen, - and others swim back on! - it all seems quite natural to me.
But I do believe that there are those who seriously think you can fit a quart into a pint pot!
