@alexandreborges Hi, I already implemented this locally and would like to contribute to the repo. I don't have access though.

Dear @zenityinbar , that's a good contribution. Let me explain what I'll do this week. In the next days I'm releasing a new and full-refactored version of Malwoverview (another project). Soon I do it, I will also create a "dev" branch of this project for people to be able to contribute to this new branch. After changes and tests being performed, so we migrate changes to the master branch. What do you think about it?

Hello. I thought I had already answered, I apologize. I'm just happy to contribute at whatever timing is convenient to you :-)
