Can Synfig do frame by frame?(Traditional)

Can Synfig do frame by frame animation or can it only do motion tweening stuff? For example: Can I import a scanned drawing and color it in Synfig and use it as a single frame, or can Synfig only use motion tweened shapes? I’ve tried different methods to create the frame by frame effect but I can’t seem to figure it out.
So my main question is this:

Is Synfig only meant for motion tweened shapes, or can it also do frame by frame animation like Adobe Flash?

It is oriented towards tweening, but it can do still images, so you should be able to do frame-by-frame. You might want to check out Pencil for something that was designed for traditional animation. See the related projects page on the site for the URL.
