I was trying out a new long form note editor that supposedly had the ability to schedule publishing. It didn't work, It published when I hit post and not when I scheduled. I'm still in the market for an editor that will let me schedule when a post goes live.
Habla.news will let me get it ready ahead of time and all I have to do is click publish. That is the best I've found. Highligher.io, which I used for this post, also won't let me do block quotes which I use a bunch, so I'm probably back to Habla. Highlighter does keep the headings, bold, and italics from the substack editor that I copy from and easily does lists, so that was nice, but quotes are such a big part of my posts, that not allowing quotes is a nonstarter for me.
