Thanks for the PR! However, I think it would be best if you do the following:

1. Split this PR into multiple PRs, one for each group of changes. This would end up being at least 3 PRs, due to the various changes within this one.
2. Provide a description of why the changes were made, rather than what was changed. Reviewing this PR, I'm unable to determine why the changes are required.

I will close this PR, but will be happy to review and merge other PRs.
