Update Screenshots

[xeruf]

Some Screenshots are outdated, and they all need a somewhat better description to increase presentability.

I agree. In addition the readme in general needs to be more concise and on point, more helpful and complete. This will take an effort and I may not have enough time. Objection noted, I'll see what I can do. Of course, if someone will beat me to it, I won't complain, but yes, it's been on my to do list already.
