Tip 001: Colors in the Flame-editor
You have some nice gradient, but a small part is odd? Enter Gradient-tab and press the Edit gradient button.
Move the left color-marker to the left of the part of the gradient you want to remove.
Move the right color-marker to the right of the part of the gradient you want to remove.
Press the Fade-button, now left colors is faded to right, and the odd part is removed.
