I had a question from a client recently. He uses DesignSpark for some small designs he makes himself, and has them made in China. I wrote him a little program to tweak the Gerber file extensions to suit the common Chinese standard, and he reported that this has stopped working. This was because DesignSpark has changed the naming conventions for solder resist layers from e.g. "xxx - Bottom Copper (Resist).gbr" to "xxx - Bottom Solder Mask.gbr" etc. The file names are all that exists to distimguish one file from another, there being no metadata in the files themselves.

As it's not difficult to add this, as either a G04 comment or as a TF command, I'd like to request that this is inserted during plotting in the future.

For example:
G04 Top Copper *
or
%TF.Layer,Copper,Top*%

Whatever suits the programmer!

It would still break my program if it changed, but it might be easier to detect and flag up.
