You can change styles from subpacks options, just make sure you restart the game after the changes.

And how to use the Guide UI with other resource packs?

It's easy, just place it on top of another resource pack (also with VDX UI or Old Days UI).

Upcoming features for next versions:

• Anvil Guide UI and more things!

Terms of use:

You’re allowed to:

• Make review about this pack, as long as you credit me as “@CrisXolt”. And put original download link in description (Only this post on the MCBedrock forum, NO Mediafire).

You’re NOT allowed to:

• Make customized APK/APPX and monetized content (pirate modifications), no one will have the permission.
• Steal my .JSON and .UIDX file and my code design claiming this work as your, no one will have the permission. Specially not modify/erase the text in the first line UI data in each .json file. (Example text: //File Made/Modified by @CrisXolt).
• Repost this resource pack made by me in other pages, no one will have the permission.
• Do not use for third-party projects, much less to merge with "Concept Clients" resource packs, no one will have the permission.

Now I am taking action, if you break these rules, I will directly make the copyright complaint without notice, I can't tolerate this anymore. -_-

Special Thanks:

@LukasPAH for making item_aux calculations possible for item rendering in UI.

Final note:

Seriously, those default .json UI files is made originally by Mojang and Microsoft, actually are modified by me for entertainment purposes.

Just enjoy and good luck! ;D
