I'm already using a few applications for hierarchical note taking. I like the graphical implementation as in the worklowy and gqueues.
Workflowy has nice organization of information but it lacks the feature of moving branches to other levels in the hierarchy. This feature is possible in Gqueues but lacks the nice features of Workflowy of structuring information.
Could you recommend some open source application (webbased with open source or for Linux OS desktop, not mobile application) which is such a mix of Workflowy and Gqueues? It can be GUI application or text-based similar to tudu.
It should not be mindmapping application.
