Android Studio 1.0 12 years ago
Android Studio has become a good, mature IDE. Having had to go back to Eclipse for my current project, the positive difference is vast once you get deeper into it. I still believe Eclipse is far superior on Windows than it is on Mac- the usability and scrolling performance is terrible on retina Mac.
This brings me to my most wanted feature in Android Studio - smooth native scrolling! Right now it scrolls lines-at-a-time rather than pixels-at-a-time, which is slightly annoying. Eclipse on Windows was very nice in this respect.
