Enhancement: Possibility to add personal comments in the detailed description

[gerion0]

ArgoScholar is a really nice tool to explore the personal network for an own paper.
However, often one want to leave some personal notes to a specific citation (after reading it, for example to leave some comments how exactly it fits to your own paper).

It would be really nice, if those notes can be added as part of the window at the right side with the details of the citation.
Maybe it could be even more generic and one can add arbitrary key, value pairs. With this, for example a bibtex key can be added to connect ArgoScholar with preexisting bibtex files etc. or adds the ability to integrate ArgoScholar in some preexisting tooling for citation searches.
