It would be great if xcoms carefulBreak from carpetmod112 is also available in carpet-extra.

what's careful break?

when you break a block while sneaking the block directly goes in your inventory

That's a scarpet feature, see https://youtu.be/g7Ku73ElDBs

yep - such features should not be implemented as mods. Noone gonna maintain them. Use a script instead and customize it to your liking.
