Why can't I have multiple main ideas?

Question

It seems silly to have only one main idea be permissible. Why not let me have multiple root objects? I want to be able to track my entire project on one graph.

Answer 1

With this tool, our idea was to have a single root object. It eased the creation of this tool.

For multiple ideas in a single map, you can create a normal root and multiple ideas as subnode of root map. This has been in our mind while we developed this tool.
