For example it would be nice to group on a tag for type or city. Since there is no standard tags other. Than name it would have to be configurable.

is there any plan to integrate support for adding a pem file to the ssh?

I'm aware that @sunils34 is working on this functionality. When he's ready he'll push the fixes to the this repository.

Hey guys! I'm so sorry for my delay with this. I ended up going a bit further, yet I realized I should have submitted a PR for each individual improvement instead of bunching everything together. I'll submit a PR early this week for .pem file support.
