1. Click options
2. Select "Save Fractal"

User shall not be forced to enter a name at all, or a good suggestion shall be 
made. Now an empty field requires input of a name.

It is hard and timne-consuming to find the satisfying parameter configuration 
that produce the fractal images.

Frex could help users finding parameter configuration by an evolutionary 
approach: 

In an inital step, Frex generates, say, 4 random fractals.
In successive steps, the user selects the most interesting one and Frex 
generates 4 slight variations of the theme. This loop contiunues until a 
satifying configuration is found.

Frex currently (1.1.1) has a fixed set of gradients. Frex should be able to 
generate random gradients (e.g. generated from Sine superposition).

The fractal manager will be used to open, rename and delete saved fractals.

Users can currently only delete *all* fractals.
Users shall be able to rename fractals and delete selected ones (including all).

The fractal manager will make use of the Gallery view (as it is done now in the 
"Open Fractal" dialog).

Add option to delete single, user selected saved fractals. Users can only 
delete all stored fractals.

Spinner background shall be dark, font shall be bright.

Selecting 'Manage Fractals' sometimes leads to a Frex crash.

A welcome screen shall tell the user how to use Frex. It shall only be shown 
once.

What steps will reproduce the problem?
1. Select "Save fractal"
2. Fractal data will be saved in Android/data/nf.frex.android/Pictures
3. Open device's gallery --> The fractal images will not appear

The stored fractal images shall appear in standard gallery as album "Frex", but 
Android/data/nf.frex.android/Pictures is private.

Fractal details are often are not aligned with the screen boundries. A 
two-point rotation should enable the user to align the current picture detail.

Frex shall registers itself as a handler for the file extension ".frex", so if 
the user attempts to open a file named "wonderful.frex" Frex would launch and 
receive an Intent containing the information on the file’s location and its 
data can be imported. 

Observed on Android 2.3.3 only.

Reproduce:
1. Zoom into fractal so that it is regenerated
2. While it is computing, change device's orientation
3. Frex crashes

On orienation changes the fractal shall simply be regenarated, or  orienation 
changes shall be disabled.

Make Frex spanish.

Two finger zooming does not animate on some devices, e.g. Samsung S III with 
Android 4.1.

Users should actually see continuously scaled versions of the current image.

The device's back button may be used to navigate back to the last region. Users 
shall be able to control the behaviour.

Problem occurs on some devices when setting wallpaper:

java.lang.IllegalArgumentException: width must be > 0

On many Android 2.3.3 (SDK 10) devices (e.g. HTC Wildfire) the option menu's 
background is light grey while Frex' action icons are white so that they are 
barely visible 

Find way to to turn the option menu's backround dark grey.

Use RenderScript to accellerate fractal computations, 
see http://developer.android.com/guide/topics/renderscript/index.html

Steps to reproduce the problem:
1. Generate image
2. Store image
3. Open image manager
4. Select image, press send action (e.g. target gmail or WhatsApp)
5. Image will not be send (e.g. mail with empty attachment) 

Frex should come with a predefined set of fractal images where users can start 
from
