Interesting idea. While first browsing your post I even thought to read "save profiles to files". But I guess you mean to save the profiles within the application and select them through some form of switch in the GUI. I'll put both ideas to my list and will consider implementing them. It can take a few weeks to months though...
Thank you for your feedback! This is just a basic tool, but that's mostly because it was only designed for my personal needs and there wasn't much feedback yet. :-)
