I won’t let this thread burry itself, although full text notes are great for discoverability, oftentimes a small doodle is worth a 1000 words, and not having drawing capability risk pushing people to write a complete wall of text just to describe what they could easily do in a table (hard enough to do in markdown without friction) or a free hand diagram.
Markdown is nice to be editor neutral (postly), readable, but should not become a liability because “markdown doesn’t support this”, drawings especially vectorial can be edited, saved and displayed in the current Obidian version (svg / pdf) and drawings are supported in most note taking app as a core functionality.
Nothing against plug-ins but in the end i don’t really want an app that does almost nothing by default and needs a plugin for every single thing, and a workflow that has to launch an external app/save export as image/import in obsidian is way too much friction vs. trying to describe the diagram instead of making it.
Could also double up as an image annotation/crop/highlighting tool for regular images.
