@Alcom Isst. I Believe this might interest you. In fact, it was you who inspired this whole thing in the first place!!
I too have been frustrated with LDD's tight field of view. So I decided to do some trawling to see if I can fix it. Short answer: yes, sort of. Long answer...
We all know of the .LXFML, how it's used to define bricks and their positions, colors, materials, and decorations. However, there's an entry near the top of the file containing this...
<Cameras>
<Camera refID="0" fieldOfView="80" distance="74.432579040527344" transformation="0.4940568208694458,0,-0.86942952871322632,-0.37650489807128906,0.90137076377868652,-0.21395042538642883,0.78367835283279419,0.43304824829101563,0.44532835483551025,58.206588745117188,38.516323089599609,40.448169708251953"/>

There's another entry within that entry called "fieldOfView". Right now it equals 80 degrees. Alcom tried changing it, but it wouldn't work for him.
He also mentioned that the FOV changes a little bit when you move the brick selection pane. I wanted to see what he meant, so I tried it. After, previously, setting the LXFML's FOV to 35°.
And as soon as it moved, the FOV changed to 35°!!!
I also discovered that the FOV is persistant within the same instance of LDD. Meaning that, as long as you don't close it, any file you open will use the source file's FOV, so long as you don't move the brick selection pane again.
And now for irrefutable proof.
I'm incredibly stoked about this! And it's so simple too! All you need is a zip program and a text editor!
I hope this helps everyone!
