Open menu while message is on screen.

Hello!
I recently started making Visual Novel game in RMMV. I began with searching for plugins I would need for it, including YEP_KeyboardConfig and YEP_X_ExtMesPack1 (I do have Message Core). After configuring everything, I started looking for plugin that would allow me to open menu at any time and I found this: https://forums.rpgmakerweb.com/index.php?threads/request-open-menu-during-messages-plugin.56323/
Well, it worked but only for a while. I managed to make it compatible with YEP_KeyboardConfig but It wasn't compatible with YEP_X_ExtMesPack1.

What's the problem then?
Well, Choices are screwed up. It's difficult to describe. They are ok with one of those plugin, but together they make mess. In Event Editor I made "Show Choices" command with 6 options, so output should show only 6 of them.
While scrolling down, it shows:
1 2 3 4 5 6 1 2 3 4 5 - (repeat)
While scrolling up, it shows:
1 - 6 5 4 3 2 (repeat)
(note: I used "-" symbol to show sittuation, where all the options disappear. (see attached file)
Really weird...

I tried to remove lines of code that could make this problem. Everything was cool, until I closed menu with choices onscreen. There was an error: "can't read bitmap property".

That's why I'm here. I'd like to make a plugin suggestion.
I need a plugin that will allow user to enter Menu while Message/Event is active AND will be compatible with Yanfly Extended Message Pack 1. It'd be cool, if user was able to configure input. (I use ('menu' || 'escape') by the way).

I feel like like I require too much... Well, I can't JavaScript so I hope someone will be able to make a plugin or fix...
Anyway, if you are going to do something about this, I wish you good luck and thank you in advance!
