Which IDE will suit agile development at its best? When I talk about agile, I primarily think about refactoring flexibility, powerful code browsing and all kinds of code inspection / warnings tips (similar to JSlint etc). Optionally, SVN/GIT integration would be nice to get supported as well as an ability to run both on Unix and Windows. Freeware or commercial – both options are valid.
Update: read this post, but the tools there support mainly Microsoft platforms (which is good thing, but alternatives are welcomed as well).
Finally chosen IntelliJ Idea Ultimate Edition – works out of the box, has an impressive code browsing and refactoring capabilities. Tried Eclipse and other related vendors, but (personally) found the installation procedure not that as 1-2-3 clicks easy as expected. All that said, this is only my personal subjective impression.
