Is there a tool similar to maya's "edit edge flow" in blender I personally enjoy modeling in blender more than maya, but this one tool is so extremely helpful. It should be included in blender if there isnt something similar already. Is there a place where I can suggest tools?

Heres an example

Not exactly, but there are some tools which you can use to get similar results in specific situations.
Shrink/Fatten (Scale along normals)
Press AltS

Smooth subdivide
Change Smoothness in the redo panel (F6) after subdividing

Smooth loop cut
Change Smoothness in the redo panel after cutting, or set the smoothness while positioning the cut with AltMouse Wheel (the smooth value is displayed in the header).
