The failing build seems to be a network error.
@erezrokah can you please investigate?

Thanks @bradystroud!

I haven't tested it yet, but added a few comments on the code

Hi @taineriley1 and sorry for the late review.

Added a few comments.

Also, during my tests I noticed the Save notification hides the delete button.
I'll check if we can move it a bit down.

Hi @erezrokah,

Thanks for the suggestions. I have implemented this in the latest commits and the code is much more readable now.

Thanks,
Taine
