I'm using GIMP every day (on 11.10). Because of this, I need the Single-Window mode feature.

So, I've added the [matthaeus123/mrw-gimp-svn PPA](https://launchpad.net/~matthaeus123/+archive/mrw-gimp-svn), but as you see the description:

>

I had to install them. The Gnome3 repo is quite OK, but the Ricotz Testing is full of new unity and other not needed update.

As the result of the previous, **I'm experiencing some UI inconveniences**. (Eg. the backgrounds and the text colors of the indicators' menus are nearly the same - so hard to read them.)
(As it is shown there:)

I've googled around about repo prioritizing, and I've found the repo host pin option:

```
 Package: *
 Pin: origin "ftp.debian.org"
 Pin-Priority: 400

```

It is too much! I've other PPAs, whose are OK. I wanna just the bad one: [ricotz/testing](https://launchpad.net/~ricotz/+archive/testing).

I've heard about [PPA-Purge](https://launchpad.net/ppa-purge). So the downgrade won't be a problem. **I just wonder the prioritizing of the repos, OR other sources of GIMP Single-Window mode+Gnome Shell(3)**.

Please help me! Thank you!
