Current Scope

Dedicated pocketdims:pockets dimension.
Per-player private pocket cells spaced far apart inside that dimension.
One short-lived "open in front" pocket window.
Two temporary portal slots and one permanent portal slot per player.
Temporary portal slots close automatically after 60 seconds.
Portal size and orientation are configurable at summon time. Current size bounds are 0.5 to 8.0 blocks for width and height.
Summoned vertical portals spawn 3 blocks along the player's exact horizontal look direction and face back toward the player for sprint-through entry, including diagonal angles.
If the player is falling while summoning a vertical portal, the source portal becomes a floor catch portal below the player and fall distance is cleared after crossing.
Pocket-side entry anchors can be changed while standing inside the pocket dimension.
The last outside portal location is remembered, so players inside the pocket can open a return window.
Pocket cells start at Y=160. The default platform is generated once, then left editable.
Pocket portal use now emits a lightweight space-bending aura around the player, including subtle portal particles and nearby projectile warping.
Optional Unique Systems integration requires the player to own pocketdims:space_bender before pocket commands/keybinds work.

/pocketdims open is context-aware: outside the pocket dimension it opens an entry window; inside the pocket dimension it opens a return window to the last outside location.

Keybinds

The mod adds unbound controls under Immersive Pocket Dimensions in Minecraft's Controls menu:

Open Pocket / Return
Open Return Window
Create Temp Portal 1
Create Temp Portal 2
Create Permanent Portal
Close Temp Portal 1
Close Temp Portal 2
Close Permanent Portal

When Unique Systems is installed, that mod overrides these labels with obfuscated names and the server hides/denies the commands for non-owners.
