LGTM, seem to have a lot of overlap with #66, I'm not sure whether order of merging will be relevant.

[Murugan-Maniish]

Am I right to assume this PR should be merged before #66 since the command wouldn't work without the this?

[Ko-Khan]

I think filter by status should be merged first. This is an extension of that pr.

[Murugan-Maniish]

Good job fixing the comments
