Notepad++ has a feature that I would love to see in IntelliJ: Indention lines. This was previously requested by another user and marked as "Will Not Fix" (see http://www.jetbrains.net/jira/browse/IDEA-13593). I could not see any way to reopen the original request. In my case, I would like to see this feature limited to specific file types. I don't want this feature for Java files, but I really want it for JavaScript files. Many of the popular JavaScript toolkits (dojo, ext, yui, etc) encourage styles that result in much deeper indentation that Java files. I currently have enabled: "Highlight Current Scope" and I have tried "Show Whitespace", but neither is as useful as Indention lines (especially since we use spaces instead of tabs). As a workaround I currently use an "External Tool" to launch NPP and modify my JavaScript files using that tool. Not a good solution. Long live IntelliJ! I'm up to 8 years as a dedicated IntelliJ evangelist.
