Don't get too excited about these sophomoric features. All modern IDEs have copied the best features from various editors. You can get the kill ring and set mark in IntelliJ, for example, and various other things besides.

These features are all simple hacks from twenty years ago. What's really difficult is putting in the elbow grease to polish the environment to a shine of high productivity, which is where buying a commercial IDE is a win. Code completion works better. Refactoring works better. Fuzzy completion works better. The keyboard shortcuts won't put you in the hospital. But mainly, code browsing in large, complex code bases works better.

It's really hard for people to look around and realize that times have changed, and change with them. People learn one thing and then their ways are set. It's up to the next generation to move things forward.
