I've been pretty busy lately. I'm working on it during weekends, so therefore I'm not making progress as fast as I expected. I will let you know when it is ready to use.
The SS-sorting program works fine now, I sorted 365 screenshots and there wasn't a single mistake. However, name recognition is giving me some trouble, and it might take a while to get it done. In the meantime if any of you need your screenshots sorted, drop me a PM on discord (Osolnik#0356) and I can change the code to make it work for every individual.
I've made some changes to it as well:
If there are two kills on the screenshot, it only counts the last one. Reason: I usually take a screenshot every time I kill someone and I think the majority of members do so as well. That means that you can have a kill on the screenshot, that was already recorded, so there is no need for duplicates.
When you are done with the sorting, the program lets you know how many kills you've made with each weapon so far so you don't have to check each folder.
