I love the portable crafting table, especially since I can open it with a keybind. I would love to be able to take the portable crafter out of my inventory and place it in a Curios slot instead. I was actually able to do this myself using Curios' toml settings, along with CraftTweaker to add the curios tag to the item, but the keybind doesn't work when it's in a Curios slot. Not sure if adding Curios support is outside the scope of this mod, but it would be an amazing feature.

For those who use Curios, it would solve the desire to have a 3x3 crafting grid replace the 2x2 grid, which I know you've already considered and determined doesn't work well in the GUI.
