That animated cursor move effect is very interesting! I wonder if it could display extra information for the user, with some tweaking. Trying to think of some things that we do subconsciously while navigating code...

Moving across a code block with "{" and "}" could highlight the parentheses and the link between them, for a fraction of a second.

Highlighting or landing on a variable could send a tiny zip of pixels towards the nearest uses of that variable.

I've wondered sometimes if making the current function or block pop a little brighter than its surroundings could also give your subconscious mind a bit more information.

All these would have to be incredibly fast animations, just a few ms would be great for me. I loathe the slow-to-me animations in Android, and always use the dev tools to speed them up.
