I have been using Eclipse 3.2 and WTP 1.5 since last Friday afternoon. Let me say I like what I’m seeing.
One improvement made in WTP 1.5 that I really like is the fact that when using the J2EE Perspective and looking at my Project Explorer I see the projects I’ve created. The key is that I’m not looking at a bunch of high-level groupings that my projects fall under. I hated that I had to dig through the various project types to find my project. There was no reason to have the J2EE project types listed there. Good move getting that out of the Project Explorer.
