In the game the command helper is fine. This is an good work.

But any funktion must have.

When a command is written, it should be possible for the tab key to work. Even if I remove part of the command.

In the examples, I have the missing functions of the tab key
Arrows [↓] replaced.

Parts marked with [X] are missing completely in the structure. !!! No helping for DATAS !!!

In this case, which appears in all commands, I want
just replace the coordinates with another.

Example: 1a. / setblock 12 13 14 minecraft:skeleton_wall_skull{} replace
                1b. / setblock [↓] minecraft: skeleton_wall_skull[ ↓

↓ ] [ ↓ ]
2a. / setblock 12 13 14 minecraft:skeleton_wall_skull

replace [ X ]

The quick flushing out of small parts with the aid of the tab key did not work in any way.

That's absurdly important. Please Fix Bit.

Thanks PCobald
