Converting Command Block Chains into Functions
A new button has been added to the command block interface, allowing you to export a command block chain as a datapack function.
Alternatively, you can press F10 while in the command block interface, or hover over a command block and press F10 to open the conversion screen.

Export screen showcase

The mod also provides an option to remove the entire command block chain and replace the first command block with a call to the newly created function.
Important:
The start of the chain is defined by the command block from which the export is initiated. This allows you to convert only a selected portion of a command block chain into a function.
To export the entire chain, you must open the export screen from the command block at the very beginning of the chain.
Additional
To select the datapack you want to edit, press F8 (or any key you have bound to this action).
