When I break a traffic signal, stoplight, etc. it drops the pole with the NBT of the light. Wrenching it off is handy, but I think it would also be nice to drop everything when it's broken, rather than saving it in the NBT.

Also, decors and poles drop in creative, it would be nice if they didn't - Ooferine

Finally, it would be nice if you could lock text signs for servers, if there isn't a way to already.

Last one exists. Will tweak the former two prior to release day.

Addressed in 5a186cb

Fixed in V18.0.0.
