This has been quite a problem to the new OreUI design when the textures for the HBUI is in the wrong folder. It makes changing textures of the new UI so much harder compare to regular JsonUI. So what they should basically do it's move the gui\dist\hbui inside the resource_packs folder

Current location: <minecraft_version>\data\gui\dist\hbui

Moved location: <minecraft_version>\data\resource_packs

If the texture files for the OreUI is located inside the resource_packs folder, it should makes modifying textures for the OreUI screens so much easier via different resource packs
