@cesswairimu @jywarren , @Kennygrace needs to be assigned to this issue, they have an open PR at Kennygrace#1.

I decided not to type up extensive issue notes if the contributor already has an open PR, I thought it would be overkill since it seems as if they don't need the help.

[cesswairimu]

Sounds good, thanks @noi5e

[Kennygrace]

@noi5e This is what I worked on, and I made a PR already, should I do it again?

[noi5e]

@Kennygrace no definitely don't do it again! I've linked to your PR here, so hopefully @jywarren or someone else will review it and merge it soon.

[cesswairimu]

@Kennygrace, it seems you made the pull request on your repo, you can create one on plots2. Thanks
