Auto Tab is a plugin for Gedit that auto-detects indent settings (width and tab/spaces) in source files and adjusts tabbing accordingly for each buffer on the fly. Useful for people who are working on multiple projects or with other people's code, as coding styles often vary and needs to be preserved. Note that Auto Tab does not reformat or change the source code to use your favorite tab length - this is for the developer that wants or needs to work with the source as-it-is.
