Many users including I use Obsidian for keeping track of various tasks, and have different task statuses like incomplete and various others as shown in the Tasks plugin documentation. Out of the box (no community plugins), Obsidian only supports unchecked and checked statuses, no matter what is between the
[ ] box.
Obsidian should have a setting to enable multiple task statuses, and show whatever regular font character in the box, or even a lucide icon of their choice depending on what they write inside
You can show different task statuses with CSS since the HTML elements for them have attributes for it, and you can use 3rd party plugins for managing them, including the Tasks plugin.
