Many folks have written me to explain that they don’t use Obsidian because there is no live preview of the Markdown syntax.
The Obsidian team is now firmly in the process of knocking that particular domino over. I’ve been using it only a short while, and it works as expected. You type Markdown syntax in, and Obsidian renders it as rich text (including links). I’m happy they’ve added this feature, though I expect I’ll still be doing most of my writing in Obsidian in plain Markdown text. The beta live preview mode is now available for Obsidian Catalyst supporters. It’s only a question of time before everyone gets it.
