CyclopsMC/ColossalChests#58 shows that this mod has performance issues when interacting with Colossal Chests.

Because of this, I have implemented a simplified variant of the IItemhandler capability which is exposed by the Common Capabilities mod.
This is required for mods like Colossal Chests that expose a huge amount of slots, which does not scale well for item transfer when a slot-based handler is used. This is not a performance issue of either mods, but simply a direct consequence of the slot-based IItemhandler capability.

The new ISlotlessItemHandler capability is slot-agnostic, so it moves the responsibility for finding items when extracting and finding locations when inserting to the capability provider. This makes it possible for mods like Colossal Chest to optimize these actions by indexing its inventories.

Let me know what you think. I'd be happy to assist when implementing this capability.

More details on its usage can be found here: https://github.com/CyclopsMC/CommonCapabilitiesAPI/wiki/Slotless-Item-Handler

The latest dev build of CyclopsMC/CommonCapabilities@2ebd61c provides this new capability.
CyclopsMC/CyclopsCore@f01eb2a and CyclopsMC/ColossalChests@4bf524e have also been updated to provide an efficient implementation of this capability.
CyclopsMC/IntegratedTunnels@034c933 is an item transfer mod that has been updated as well to make use of this capability.
