I am looking for a comfortable pdf reader where I can read articles and paper as well as annotate them. For the annotation part I would like markdown or latex support. Fermat's Library offers an online solution called Margins which allows adding comment in latex and markdown and also it displays the comments very nicely on the side outside the pdf boundaries. Please suggest some alternative solution to it which does the same. Here is some feature I would like.
- open source
- offline
- available for linux.
Thanks in advance :)
