Raphaelz, regardless of the quality/status of your code, you might want to upload it to a repository such as google code, github, bitbucket or sourceforge.
Perhaps some other people want to have a look at it and may have improvements... of course I understand that you would rather clean things up if it is hardly understandable, but even then, you can always warn people

(Edit: and once you put it up on bitbucket etc, you can still edit the code and upload the changes using subversion, mercurial/hg or git...)
Finally, depending on the devs, and your modifications, it may well become part of the official code for the people that prefer a single window setup...
