If I search multiple files and then select one of them the DIFF display jumps to first match (as I have selected in OPTIONS). But that is positioned at top of screen. At all other times when I use NEXT / PREVIOUS the match is scrolled to mid-screen. Nowadays I have huge (portrait) screens, so the difference in placement is significant, compared to the Old Days ...
If the first and second match are a few lines apart it is "annoying" that the first match is at the top of the screen and then when I use NEXT, even though the next match is a couple of liens away, it scrolls to mid-screen.
I think it would be better if:
First match is mid screen
Unless first-match is so early in the file that is above mid-screen, in which case position screen with 1st line at top-of-screen, and highlight match accordingly. (No scrolling on NEXT until a match is below mid-screen position)
