-Calendar and task list for Obsidian Kanban+Tasks
+A calendar and a task list for Obsidian on top of Kanban boards and the Tasks plugin. A sphere is a board file, a project is an h2 inside it; every task keeps living in its board, the plugin only shows them together - by deadline, by sphere, or on a month grid - and lets you drag, edit and close them without opening the board.
 
-Sphere - md-file in Kanban boards directory. Project - h2 inside the file.
