For example, we have a mesh of complicated shape and made of evenly distributed polygons. So flat surfaces and relatively curved and sharp ones have similar polygon density, which sometimes is not rational. Flat surfaces can be drawn by less polygons and curves need to be more detailed to look smooth or properly sharp.
Idea is to make a tool, that would preserve basic shape of mesh and create new topology for it, approximately based on user defined quantity of polygons per arc angle. For example: Curve turns on 15 degrees & gets one polygon, no matter of curve's size.
So flatter surfaces get less polygons and curved surfaces & corners concentrate polygons.
There also can be an adjustment for lonely one-edged sharp corners, that would work like bevel tool. Distance to define corners as lonely must also be adjustable.
This tool, combined with vertex slide, will simplify creation of complicated shapes with rational topology.
Also it can be used dynamically with sculpt, so, for example, mesh will get new polygons when adding a big sharp bump on it, and remove unnecessary polygons when something is flattered.
