Add a new element to the game called CCNV (Conditional Converter)
which would change any block in a 3x3 area around it which is of type (tmp)
and change it to type (tmp2)
Although elements would have to be set using their number identifier,
I think that it might allow for a larger range of compact electronics and machines
Or even have it change the element of type (tmp) to type (ctype), to make it easier.
Or, better yet, change CONV to have this feature, kinda like VOID does.
Just my thoughts, but it's definitely something I'd love to see in the game- in the past, I've had to use STOR+PIPE+CONV to get this effect
Okay, try to not be too surprised, but CONV already does that. Apparently it's been doing that since late 2015. See the save below.
