Basically, that mod switch the Gamerules button to open its menu instead of vanilla one, and i Reimagined Menus override that.

If you can detect whatever that mod is present and keep its behavior would be amazing to have.

any news? @lamaprogramer

Not at the moment, been busy with a bunch of other stuff, so I haven't gotten the chance, I'll take a look at it whenever I make my next update.

Should now be added in version 3.0.0.
