While Galileo is out for a while I switched just last week to the new version.
What I really bother about is the lack of extension locations (about which I blogged already about Ganyemde).
But now I gave up with it and switched to .link files to share my plugins for my different eclipse versions.
The most important thing for me in the new release happened behind the surface. I am a Mac user and after Carbon is out I already followed the milestones of Galileo in Cocoa.
It is great how fast the SWT team has ported because I think that was not quite easy.
The coolest new feature in Galileo is block editing. That rocks and was one of the missing features which urged me to open an external editor. Thanks a lot.
