Yes, and it's a recurring theme. In Portuguese we have a word "esmero", which is very applicable. It means something made with extreme care and craftsmanship.

For example, I once needed to take a very precise crop off a screenshot, and thought "it would be nice if there was a way of fine tuning the mouse position". My first thought was somehow using the arrow keys, I pressed one of them and voila! The mouse moved a single pixel in that direction.

It's hard to pinpoint in specific features, but the best description is that ShareX is a very well laid out workshop, with everything within reach and nothing in the way.
