**Release Date:** TBD **Release Date:** TBD
#### New Features #### New Features
* Added a new Matrix shader which dissolves your windows in a shower of green letters. You can switch between the fire and the matrix shader in the settings. Sadly, this effect cannot be available under GNOME 3.3x as it was apparently impossible to set textures for a `Clutter.ShaderEffect` in GJS back then.
#### Other Enhancements #### Other Enhancements
* Refactored the code a lot to make it easier to add new shader effects in the future. * Refactored the code a lot to make it easier to add new shader effects in the future.
* Tweaked timing of the fire shader. Previously, the fire became invisible quite quickly. Due to this new animation timing, the default animation time has been reduced to 1500 ms.
