0.2.3

New

• One-key collect (the square on the left of the panel's bottom border): moves everything in your inventory that already belongs to a cache cell into it, up to that cell's capacity; anything above your return limit is handled by your return settings.
• The panel can fold away completely (the square at the bottom right): folding leaves one small entry in the same place, and that area goes back to JEI's bookmarks; click the entry and the panel comes back, cell for cell identical to before.

Improved

• Cells no longer move when you upgrade the cache: an older save re-arranges once the first time you open the panel (nothing is lost and no counts change; a level-1 item does not change at all), and no later upgrade ever moves anything.
• Drop an item anywhere on the panel and it stores itself; one-key collect also works in creative mode, and the save format is unchanged.

Please note: this version re-arranges the cache cells of an older save once.
