I\'m trying to get multiple tabs in windows like vim does it. In vim tabs aren\'t tied to buffers and you can have multiple tabs each with multiple splits and buffers in them. W
You can do C-x 4 c to clone a buffer : create an indirect buffer that is a twin copy of the current buffer. It allows you to show the same buffer with different major-mode enabled in different windows.
Then with tabbar you can have different tabs showing the same buffer in different modes for example.
