[Note: Does not work in Eclipse 4.x]
You may know that one can split layout the editors in Eclipse by dragging the editor tab to any edge of the editor area. This works only if you have more than one editor. However there are times when I want to work on two parts of the same file. To do that I first do Window > New Editor to duplicate the editor and then drag it to split the editor in a side-by-side or top-bottom layout. But that is too many clicks and drags. I developed a simple Eclipse Plugin which will help you split the active editor either horizontally or vertically with a single click. It is based on some code I found here that was written by Dimitri Missoh (thanks Dimitri - I have given you credit in the source code of the plug-in). I adapted his code to suite our purpose.
Here is the screenshot:
Split Editor Plug-in is available on Eclipse Marketplace!
You can install it from the plug-in's update site:
