I've been using Ulipad[1] yesterday, and code autocompletion was amazing, at least with Python.
It also has the "split window" option, in vertical and horizontal way, something that some of us needs often.
There are some interesting things, i.e. code snippets support, and ftp/shared folder support for editing remote files, but I didn't have time to test it.
As a drawback, it is not as fast as geany, mainly (IMHO) because is implemented in python+wxWidget, which also makes it look "out" of the look and feel of my desktop.
Maybe we can import some ideas ;-)
