1 - Make old_views store the fractal type (or clear the old_views list when changing type if lazy).

2

3 - Make Fractal derived classes have unique type ID's that can can be used to identify the fractal type. Need this for the good old_views solution.

4

5 - Find out how to save jpg or some other image format that allows comments I can use to store calculation data.

6

7 - Read saved image and continue calculation.

8

9 - Zoom feature that zooms in while staying centered on the same spot.

10 - Unzoom feature that enlarges the area while keeping the image cenetered on the same spot.

11 - Pan feature to let you move side to side while staying at the same zoom level.

12

13 - Windows file handling

14 - Better file handling in general

15

16 - real GUI interface

17 - gtk?

18

19 - More color options

20

21 - More factal types

22

23 - Fix the lag of the selection box. It needs to appear instantly and in the exact place the mouse is clicked.

24 Using a timer callback function and SDL_WaitEvent is noticably better

25 than my wait_event_timeout() function

26

27 - Clean up the fractal class. No more direct access to fractal settings.

28

29 - Performance improvment ideas:

30 - Create a partial rendering mechanism.

31 OK - Use window events correctly to determine when a redraw is needed!

32 OK - Use a better way of handling events. A timer callback and an SDL_WaitEvent/ SDL_PollEvent combo. See here http://people.freedesktop.org/~idr/OpenGL_tutorials/01-SDL-intro.html
