I've made a small package of notify-osd[1] with leolik patch.

This provides extended functionality by a '.notify-osd' file on user's home. This can be either edited or managed with NotifyOSDConfiguration (notifyconf, not provided).

The contents of the file are pretty much self-explanatory:
Code:
slot-allocation = dynamic
bubble-expire-timeout = 10sec
bubble-vertical-gap = 10px
bubble-horizontal-gap = 10px
bubble-corner-radius = 50,5%
bubble-icon-size = 36px
bubble-gauge-size = 5px
bubble-width = 320px
bubble-background-color = e0d6ba
bubble-background-opacity = 100%
text-margin-size = 15px
text-title-size = 100%
text-title-weight = bold
text-title-color = 008000
text-title-opacity = 100%
text-body-size = 100%
text-body-weight = normal
text-body-color = 152114
text-body-opacity = 100%
text-shadow-opacity = 25%
It replaces the standard notification-daemon for GNOME which can be safely removed before install with: 'zypper remove notification-daemon' or just 'rpm -e notification-daemon'.

Then you can install my RPM through your preferred method.

Glad to help if you were searching for it! Feel free to post your screenshots and your .notify-osd tweaks.

notify-osd-0.9.29
/* with leolik patch */

Canonical's on-screen-display notification agent, implementing the freedesktop.org Desktop Notifications Specification with semi-transparent click-through bubbles.

The freedesktop.org Desktop Notifications Specification provides a standard way for applications to display pop-up notifications. These are designed to make you aware of something, without interrupting your work with a window you must close.

Notify OSD presents these notifications as ephemeral overlays, which can be clicked through so they don't block your work. It queues notifications, to prevent them from flooding your screen. And as well as handling standard notification updates, Notify OSD introduces the idea of appending — allowing notifications to grow over time, for example in the case of instant messages from a particular person.
