This is a plugin for Obsidian (https://obsidian.md).
If you're used to software like Notion, going from assisted markdown to plain markdown may be a bit hard if you're not used to it. You'll probably have to work with a cheatsheet open in a tab in order to make sure you're not doing it wrong.
Also some syntaxes are a bit cumbersome to write like the table one.
So, if you're learning markdown or too lazy to write a table, this plugin is for you.
All you have to do is to write a > whenever you want in a file, then make your choice.

Trigger character Set the character that will trigger the commands.Simple commands Insert commands without examples.
First, you need to have Obsidian v0.12.17+.
