This feels shallow, but one of the biggest things keeping me from using zed is the lack of a good default dark theme.
The defaults all feel very low contrast, gray on gray that makes the experience feel dull and off putting to me, even if the editor itself is great.
It should take less than a minute to install a nice, high contrast dark theme, if you just search for the theme inside the Extensions window in Zed.
But I understand your point, no reason for it not to come with a couple good high contrast dark themes.
Try this one, it’s my recent favourite and very polished: https://zed.dev/extensions/amp-theme
Zed generally feels very engineer-designed and not in a good way.
It's not just you and it's not just Zed. Dark themes tend to be low contrast gray on gray.
I usually look for a dark theme that looks good and then make a custom version with darker the background colors and brighter the foreground colors.
Maybe it's time for to start publishing high contrast dark themes instead of just fixing it for myself.
