I was on a holiday and worked from time to time on a zooming feature. Ie, where you can zoom in/out on the battle field using your scroll wheel. I found it a quite neat feature in C&C Remastered (and in the Golden Path dune remake).
I had to dive into real old rendering code, and I really had to restrain myself from rewriting stuff (pitfal!). The result so far is that I can zoom, but rendering is far from perfect. It also is unstable. Hence, see this github ticket: https://github.com/stefanhendriks/Dune-II---The-Maker/issues/65
