With this one you can zoom all you want into units and buildings!

And this great mod by @Gedemon changes the perspective. Now the icons are not so big and it looks as it must. With the closer objects closer to you!

Thanks, but I prefer to get my mods direct from the authors, from this very forum. Not from mysterious mediafire downloads repackaged with who knows what.
