Just a few questions if you don't mind:

• Is this mod built heavily or partially with AI? If so, we will still allow it but it is requested that you specify an ai property in your theme.json file with a value of "partial" or "yes" depending on how much of your program was built solely with AI.
• There is a bug I noticed that appears quite odd. The text for the Open in Container Window option appears twice (as shown in the picture below).

oh shoot! I've seen that a few times but i thought i fixed it
And yeh this is made with AI (solely)
I will put in the ai property in the theme.json
But is there a template like how to put the property in the theme.json properly?

[CosmoCreeper]

No worries, I just made a pull request to your repository that adds the ai property.

[t4nk3rchu]

so i merged your pull request now
And for the bug, I tested it with a clean profile but it does not show on my end tho.
Can i ask what other mods did you use? (originally the bug happened in my case because of CMI but it has already been fix)

[CosmoCreeper]

So I experience it only on the first install it appears.
I'll double-check everything and if it works without any mods but it enabled then I'll merge it.
