Hi @possumbilities, please I just updated the branch.

[possumbilities]

@JennySimen All seems sound, looks like that last PR merge made this out of date again, if you can do one last update we'll move forward with it after a final test on this end. ❤️

[JennySimen]

@possumbilities on it

[JennySimen]

@possumbilities I have updated the PR

[possumbilities]

@JennySimen Great work!

Something I've noticed, it might be worthwhile to incorporate the work from #162 from @ImaJin14 so that they don't conflict with each other, and I can then give credit to both of you on this PR as combined work?

@ImaJin14 You OK with that?

[JennySimen]

@possumbilities I agree

[ImaJin14]

I agree @possumbilities

@JennySimen please go ahead and implement the changes in #162

[JennySimen]

@possumbilities changes have been added on this branch

Closing with the acceptance of:
