Sam., I just wanted to report that while editing inventory paperdoll I am using your tool to check in real time how it would look like in game, and this is incredibly amazing experience! I have even nothing to ask - the moment I thought "I wish I could see resulting paperdoll in some better details" I noticed zoom button
I considered attaching the zoom to a slidebar instead of a checkbox to make it more dynamic, but the scaling provided by GDI+ (which I had to use because reasons) really isn't that great. I decided it wouldn't provide any significant amount of usefulness compared to the current static scaling factor to be worth the effort. If you think otherwise, I can do it, tho.
I also considered having the GUI remember your current selections between sessions, but the only truly reliable way to do so would be to write the current values to an INI file on each and every change. Writing to disk that way would considerably slow down the "instant" response I was going for, so I decided against it. If the consensus is that such a feature would be significantly beneficial, I can do it and try to minimize the impact on performance as much as possible. Just let me know (preferable sooner rather than later while the inner workings of the project are still fresh on my mind).
