Although the screen in the mod is Legacy-accurate, it is much more difficult to use because Legacy's menu was made for selecting only one pack at a time. It is also not possible to re-order packs with the current menu.

I suggest doing something similar to the Legacy Console UI pack by CrisXolt for Bedrock. It has a resource packs screen based on the old select world screen from Console Edition.

It is very similar to the old select world screen:

This screen allows you to view all the packs you have more easily than the one in this mod currently.

I was planning this, so much so that if you click and hold shift in the actual resource pack selector, the JE Resource Pack Selection screen will open.

Great to hear!

Thanks for suggesting, added in version 1.3.3
