Which bring us to the next topic in subject: I took over maintenance of this script when Silvercup mentioned that had no time for it, and I wanted to improve it for my own workflow. Since then I put effort on it for fun, mostly when I used it for my images and had found something that could be improved during the process. But in any case, for me it was always a challenge on computer programming. I do have many many years experience on the topic, BUT:
1) I do not really know the programming language (but looks familiar and similar to many others).
2) I do not really know the library used, or have documentation on it, other than browsing in the object explorer, looking into other people's code, periodically ask questions on the forum or just plain guessing.
3) I do not really have knowledge of the imaging methods and the maths used - again just guessing based on experience.
So, as you may understand, and considering that I do not really have an urge on an "official release", it will be difficult for me to put efforts on cosmetics or compliance on specific way of programming or look and feel. I'm not saying that I can not do it - although I do not know how to do a few things that Juan asked. For these I have to spend time to find out. Neither do I say I won't do it - it will just take me more time (never seem to have enough).
Simple putting it, it is not so fun for me right now, and if you wait me to implement all of these, it will take some time.
Sooo, considering that Silvercup gave the script with a "do whatever you want with it" (meaning "public domain" in my book), anyone wanted to contribute at this stage, will be more than welcomed.
