This filter is still in the beta release but I want some help testing it so see if anyone can find some problems with it. So far, it works for the setblock, testforblock, summon, and give commands. This includes data tags if you would like this to update them for Summoning Mobs holding items as well as with equipment. TileIDs do not support names yet so the filter has that code disabled. I will enable the code if Mojang enables TileID Name support in the future. Please use the data tags support of this filter with CAUTION!
To use it: Simply select a region to run the command on. It will look inside all of the command blocks to find a block ID in the proper location for each of the commands. If it finds a block id. It will convert to the item’s name.
I have also included a block look up feature so users can look up what a block Id is supposed to be without having to look online for it. Simply type the ID in the bottom field and check the checkbox above it. It will do nothing to the selected area in MCEdit, and will return a message with the item name that corresponds to the Item ID that you entered.
