In-game tile configuration UI

I’m a modder(tileset mainly) love this game but tileset modding is so inconvenience and painful.
Therefore I propose the following function.

“In-game tile configuration UI”

1.Select an object with the cursor and hit the key.
2.Open the In-game tile configuration UI.
3.The UI shows all tiles and choose a tile you wanna set to the object. You can search the tile by ID or number.
4.[Save and close]
5.[Overwrite json] or [Generate new json]

This will make tile configuration incredibly easier.
Please implement this to 0.D.

Have you tried Tileset Studio (

Thanks but it doesn’t work on me.
I can’t see the tiles tree anyhow. Import seems impossible.
