I think, it is a good idea, becaurse if players die, the stuff of them will despawn very fast, and when (he/she) can not find the die-place so fast, the stuff is away for
A little tip:
In the textures folder is the texture "mcl_formspec_itemslot.png" that is for the chest-slots. You can use the Itemslot-textures, of the Mineclone game (for
example: "mcl_formspec_itemslot.png"). Then you save storage space.
Much success with your mod!
The idea, to make a own funktion, to make a new tool kind is very nice.
I only noticed one error:
It is impossible to craft deepslate stuff. That's because the crafting recipes already exists for stone stuff.
The Islands are very nice but I think, that the mod should can work on Mineclone2 and Mineclonia too.
I know, that it is not easy, becaurse Mineclone2 and Mineclonia do not have the default mod, but it would be very nice to have Ilands in this games.
