In 1.21.120, Minecraft introduced an update to the user interface of the in-game pause screen, which made the settings button smaller and removed immediate access to viewing the players in your world/server or inviting players to your world/server.
In addition to this, the marketplace button is now located where the settings button used to be, which is causing many players to accidentally open the marketplace menu when they were intending to open the settings menu due to their muscle memory.
This texture pack changes the UI of the in-game pause menu to its pre 1.21.120 appearance, which fixes all of the previous issues.
Below is a comparison of the current in-game pause screen in Vanilla Minecraft versus the in-game pause screen using this texture pack.

(Using the pack)

This pack may not be compatible with other packs that rearrange the in-game pause menu, so keep this in mind if you already use UI texture packs.
