Non-constant frames per second can be usefull, and you can change the delay of all the images at the same time, which is usefull. However, the delay must be an integer ammount of centiseconds (100th of a second), so it is impossible to do exactely 30 frames per second.
When you import a image, the "advanced" open picture dialog does not have the My Documents folder or any desktop folders, so i have to to the full file path for the My Documents folder, which gets rather annoying. Also, When I attempted to export the gif, nothing happened so i could not export it. Another problem is when i tested my animation with transparency, the image did not refresh the backgound, and instead drew the next frame over top of the last one, making transparency completely useless.
