#### New Features
* **Effects for Window Opening.** You can now select effects which are applied on newly opened windows! I expect that there are some bugs left, so please [report any issue you find](https://github.com/Schneegans/Burn-My-Windows/issues)!
* **New Effect: Broken Glass.** Shatter your windows into a shower sharp shards! This effect can be configured so that the shards fly away from your mouse pointer position!
* The effect-configuration pages of the preferences dialog now have **Preview Buttons** which con be used to, well, preview the current settings (without having to enable the effect first).

* Added a menu entry with a link to the guide for creating new effect types.
* Added a new option to the Matrix Effect: **Vertical Overshooting**: This can add some vertical variation to the start and end position of the letter drops.
* Thanks to improved timing, the default animation time of several effects could be reduced.
