My feedback is that I prefer version 3 of the font. Version 4 is too big on the scenario screen as you say, and even on the other ones I think it looks uglier. I run at desktop resolution which is 1600x900 for me. I was originally very discouraged because the text was so small it was almost unreadable to my mature eyes.
There will not be a change to the game this time around for those fonts. To do this "right" requires extensive adjustments to the placement of the text on screen and we had too much on our plates this time around to deal with an issue near and dear to only 3 or 4 dozen players so if you have installed the fix when the new patch is extracted you will keep those same altered fonts you DLed
However, next year we will be doing some reorganization of the game screens and those new fonts and the required changes to the code will be included
v3 is more beautiful, but I use v4 as it is more readable on my monitor.
I use a 1920x1080, but 21.5" only, so I set DPI to 144 ('normal'+50%)
640x480 non-combat screens are really small on my monitor..
