Wow, this is what I have been looking for, right from the time I started investigating on using Obsidian instead of Notion. I am still new to Obsidian (and Notion too) and markdown editors in general, so have been looking around for last couple of weeks to make sense of how this tool works.
Please can I ask, what theme or css snippets have you used for the actual callouts you have displayed in the columns in the image on your GitHub page, under Multi Column Callout section (Link to image)
