I am looking for an online tool, preferably, to sketch complex research ideas.
For instance, I want to complete project
X. This project has some major component that need to be done and are somehow related to each other (imagine some arrows). Clicking on each of these major components will show some other sub-components that need to be done in order to complete this major component. Some of those sub-components could be just reading some papers. So I need to be able to put links in the diagram as well.
More ideally, I would like to have something like a citation library (something like
BibTeX) and refer to those papers in different sub-components of different projects.
I wonder, is there a tool (preferably online) that provides me such things?
