I wasn’t aware that there’s a paid version. Based on their website it does look like they have a lot of standard stuff locked behind Pro. Is it just like an additional repo or something? I’m also not too keen on the fact that the upgrade doesn’t carry over to the next major version.

I’m pretty sure that’s Zorin. I’ve never used it myself, but from what I’ve heard it might be a good choice for OP’s person.

The story of the song (English and German) is about someone releasing balloons causing a radar operator to mistake them for nuclear weapons and starting World War III.

False alarm of this nature were disturbingly common.

Edit: In the German version the balloons are mistaken for UFOs. Here’s a direct comparison between the two versions.
