http://www.intellij.net/tracker/idea/viewSCR?publicId=35348 Currently, the Code Style / Tabs and Indents setting allows you to define e.g. the tab size for Java files, JSP files, XML files and Other files. In stead of having an option "Other" it would be better if IDEA showed all the file types that have been registered to it. For example when editing Python scripts, I would prefer indentation of eight characters. On the other hand, for normal text files an indentation of four feels more suitable. Currently I can't set a different tab size for the two even though they have been defined as different file types in IDEA.
