@cjjacks Just checking if this is ready for final review or if there are any expected changes? Thanks

[cjjacks]

@nttoole Sorry for the last minute update! Was just double checking and realized that I had committed updates to the lock file which didn't necessarily belong in this PR. Should be good to go now.

Both code review and testing via GUI plugin pass.
