Wait until 2.1
Some significant usability issues in 2.0 — looks like this was rushed out the door before its time. New sibling nodes are added above (before) the current node. The outline in the new outline panel is not editable. Cannot resize images. Very limited stickers and no way to add one’s own icons to the library or a node. Formatting is garbled and sometimes lost when syncing to Mindnode 4 on iOS. Preview in Marked makes everything into a header — the result isn’t professional looking. For the money, there isn’t much of an upgrade here except for the new inspector panel (new location, not new features) and the outline view. Mindnode is pleasant to look at, but not much of a tool for actual work.
