Seems very reasonable indeed the 8 categories doesn’t fit the welcome page on desktop. Also, I’m still trying to find a good way to revive the working group category.
For the category name IMO “Wallets” seems like the natural option however it doesn’t cover everything as we’re seeing more and more wallet abstraction and different flows that are not really “Wallets”. So I have no strong opinion on this one your propositions are good. “Front-end” or “Web” might be my favourites.
As for @SamWilsn I totally agree, we’ll need his confirmation but that would be great to have both of you to take care of this category as we can expect it to be quite active.
