I made some small improvements in an existing gedit plugin for python code completion. The original post of the main author can be found here. My contribution consists of a few lines of code that enables the user to type unhindered by the window that pops up with suggestions. The window will automatically highlight methods and properties as you type along in the main window, and you can use the TAB key for autocompletion. My aim was to make the popup less obstructive and more transparent.
