Just My Sift Idea

I welcome everyone!

I have heard that it is proposed to introduce a new dimension (Sift), but so far there are no ideas on how to make it "unique". And... I have an idea*!

See:

•Leave the dimension empty by default.

•When opening a portal, create a small region (like the Old World Type in BE) at the coordinates of the open portal in this dimension.

•This region is available for a while, then the portal closes and needs to be reactivated, and, if portal opened again, a new region is created.

•In the "local sky" dimension, the color gradually changes from blue to red, signaling the closing of the portal.

•At the same time, when the portal is closed, all items remaining in the region are saved and added to the "permanent loot inventory" of the next region's chests until someone picks them up, and players and creatures return to the Overworld (to avoid the possibility of non-renewable resources disappearing when the portal is closed).

•Each portal has its own region, with its own time and "loot inventory", the data is linked to the portal.

•The portal opens when one or more note blocks are activated, and the region's seed depends on the selected sounds (key and instrument). In this case, when only two note blocks are placed, the number of variants reaches 486²=236196! In addition, jukebox can be used to create "special seeds" based on the playing disc.

•Objects and creatures can be taken out of the world, plants can be grown, and animals can be bred.

*just idea, nothing more.
