Revisions to (semi) traditional image editing. #169

Firstly in AI Editor (Old) - the Image Editor part - could we have a Save As facility (I hate overwriting the original!). Also, on my equipment anyway, one gets it looking correct in the Image editor but after saving it looks washed out (one of the reasons I don't like overwriting the original). Incidentally why does Brightness etc operate the opposite way to most conventions? That is slide left instead of right for make brighter?

Second (related) Request. Any chance we could have a better Semi Traditional Image Editor? i.e. Something with all the features (not interface) of something like Snapseed on Android. HDR etc could be very useful. Hopefully again with Save As to avoid overwriting the original Dream. Obviously a few included AI enhancements would be nice. Very low energy use would be sensible since otherwise downloading to use non-DDG editing is likely to be prevalent.
