Zed is "almost there" for me.

The theme builder is good and easy to use, and I only needed a few minutes to make my own.

Syntax coloring is almost there, but still lacking (I use C/C++) Small visual adjustment like line height in the UI text is not configurable enough (only two settings)

Scrolling should have a smooth option, nothing prevents it, it should be super easy to add, I find it easier on the eyes when I move around code, especially on a 240Hz monitor.

The editing experience is good, quick launch, no crashes, responsive, not too memory hungry.
