Feature request: Running ImageOptim repeatedly until you encounter < 5% savings

[diffen]

Generally when I run ImageOptim, the Again button makes it easy to make sure that maximum savings have been achieved. For some images, it can take two or three hits of the Again button to achieve the optimum image.

Can the shell script run ImageOptim repeatedly? This may be slightly tricky because we don't want to run it repeatedly on all files but just the files that had big savings (say >5%) in the previous run. So we may have to keep track of which files had big savings, quit ImageOptim, and then reopen it and only add those files to the queue.

Thanks for raising this Nikhilesh.
I agree it is a good idea and is something I'd like to have too - but I think the responsibility for this lies with the ImageOptim.app app itself. Could you add a feature request there if one is not open already? Thanks a lot.
