Add option in mods called main menu panorama.
add in this mod option to change this shitty lunar,bedrock,classic panorama to something other by texturepacks or from any folder user will choose when selecting panorama textures.
Add option in this mod to disable fog from panorama to make it look like minecraft panorama from 1.14 not 1.12 and older.
Add option to change in main menu panorama buttons size,texture,place to make it fully configurable.
I think it would be good addition becose in normal minecraft we can modify it by texturepacks and here we cant.
For you to know what panorama is i leave here screenshots
