It is highly doubtful that you will get a response from Rexx as he as essentially dropped support for his plugins.
He hasn't really posted here for over 6 months, other than to give a Github link to his addons.
Thank you for the notification — A real shame that rexrainbow has given up.
My games all rely on his amazing developments. Has he moved to a different platform?
Are there any alternatives to his most popular plugins?
