Some people have expressed interest in knowing what features are upcoming for the plugin, so for visibility, here are the features I'm planning to include in the next feature release. These are ordered chronoligically based on the time of first suggestion I could find. Let us know if we're missing anything.
- Allow configuring capacity at the slot level, rather than simply at the row level
https://umod.org/community/backpacks/30256-assign-spaces-instead-of-using-rows
https://umod.org/community/backpacks/39574-configure-slot-by-slot - Multiple backpack pages
https://umod.org/community/backpacks/34742-adding-rows-columns
https://umod.org/community/backpacks/37884-possible-to-add-more-pages - Feature to display the number of occupied/total slots on the GUI button
https://umod.org/community/backpacks/39440-display-slots - Command to add an item to a player's backpack directly
https://umod.org/community/backpacks/39984-feature-request-console-command-to-inventorygive-direct-to-backpack\ - Config option to disable the backpack GUI by default
https://umod.org/community/backpacks/40006-option-to-turn-off-gui-by-default - Config option to store associated entity data (photographs, sign data, etc.) in the backpack files (as oppposed to just the saving the IDs of those entities), so that the data can be persisted across server wipes, and so that synchronizing data files across servers will copy that information.
Note: We haven't started work on any of these features yet. Earliest possible ETA is April 2022.
