Godot has the functionality to allow for interfacing with asset stores. It would be really neat if Itch.io could integrate with Godot for  Godot Engine tagged assets and projects! The community  desperately needs a really good asset store and there will never be an "official" asset store that is sanctioned by the project developers but I think Itch.io has a big enough name to be the go to asset store for the Godot Engine.

You could just install the addon via the app then copy the files into godot projects as necessary, just like how you could with visual/audio assets, but a more streamlined interaction could theoretically be made. Perhaps an addon for godot that allows syncing to your itch account and installing godot plugins that way.

Would be absolutely wonderful to have a more streamlined way to do this and a better store-interface inapp. Already purchase tons from itch, would only enable me to do so more :D

Would be an interesting experiment, since seems like is possible to add your own stores to editor
