It indeed makes sense to me to add an Open Collective icon! Thanks for your help!

Thanks @Pukimaa — looks great! Left one small suggestion.

Could you also update branch? Looks like some checks are failing because it’s out of sync with main.

[Pukimaa]

Sure @delucis! We should be good to go now ^^

Thanks for your patience over the holidays @Pukimaa. This looks good to me — will aim to get a patch release out with this later today 🙌
