I have a new version (1.01) of my Thesaurus Eclipse Plug-In. I basically had a bout of inspiration while I was researching SWT. It now has back and forward buttons. I added the ability to get more entries without scrolling down the page. There's quite a few bug fixes too.
The source is included. The model has been tightened up. I moved responsibilities to where they should have been in the front place. Hind sight is a wonderful thing. I'm still having fun with SWT and amazed that it does exactly what you tell it to. It's a nice framework to deal with. It all makes sense and looks wonderful!
