I am looking for a modern, highly usable, single package IDE/wrapper for Eclipse (if such things exist). Something that would provide a wrapper to Eclipse and add some style, a nicer interface, better code highlighting, etc. Any suggestions?
Edit:
-Java
-Looking for a nicer “prettier” IDE with more visual features and code completions, etc.
-Should be able to install it on a live Eclipse install
Eclipse is one of the best IDEs in terms of code completion and refactoring features. If your concerns are mainly style, you can customize syntax coloring using the Preferences > Java > Editor > Syntax Coloring menu. Or check out color themes here.
If you want a different skin for Eclipse you could try here. There are also code visualization plugins and style warnings, but you need to be specific about what you want.
