Nice but needs some other features!

Compress images and resize them as promised, even if my late 2012 retina has some problems keeping up with its resources requests.
I would use this software alongside some other image processor (and change the valutation to 5 starts) if the following features are introduced:
1) Overwrite old files
2) Overwrite old files and keep backup in given folder

Also, i don’t get why some buttons as “export” are redundant.
Finally, the gui is not yosemite-ready.
