A good idea with a long way to go before perfection is achieved.

First of all, hierarchical browsing through all the folders on one’s computer in order to find image folders is very clumsy and un-mac-ish. Other apps have niceties like ”add folder” buttons and drang-and-drop. (Perhaps even a ”Scan harddisc for image files” menu could be useful.)

Secondly, most people do not remember pictures by colours, but rather by things like, I guess, buildings, who were on that particular photo, was it a group portrait or a depiction of a landscape etc.
I recognize that a program that can analyze the facial traits of photographed persons and group shots of similar individuals together may be a bit out of scope here, but at least it ought to be possible to do shape-based sortings like:
*images with predominant vertical/horizontal elements
*images with one central dark element
*images with several scattered dark elements etc.

But keep up the good work and this may some day revolutionize the way we sort images!

Ugly and slooooow!
What is the reason behind this?!

Just one small thing ... the open app shows the name qtimgsortv2 instead of ImageSorter in its menu bar.
