A tone equalizer in darktable ?

#1 when I complied your toneequalizer branch it noted that you are a good number of commits ahead of the master branch but the version shows as 2.5 and not 2.7 or highe

The 2.5 tag is purely a git stuff, I never updated the tags. It means nothing for the actual program.

Does using this with any files the have been edited on a 2.7 dev build create any issues with previous edits…of course i will back things up before trying but just curious

It should not create issues per se, apart from the usual “this is still unstable stuff until proved stable” I guess.

secondly other than this post are there any other examples or documentation that you have created or are aware of for the use of this module.

Not yet.
