This could just be an individual taste situation, but I noticed that the composer has a “white glow” when using the Dark Theme. It’s especially apparent when hiding the preview in the composer. I changed mine to a darker shadow and liked the result. Below is a comparison:
Default
Modified
Here’s the change I made to the Dark Theme Desktop CSS:
div#reply-control {
box-shadow: 0 -2px 10px rgba(0, 0, 0, 1);
}
This is a super nit-picky thing, but on the off chance anyone else felt the same way, I thought I’d share my solution
