I suggest an improvement to the Eraser function

In certain PDF documents one may need to completely remove unwanted objects, of different sizes & shapes, from a number of pages. These typically are: figures/drawing/images and advertisements (again, in the form of pictures or text blocks). This can be done using the program's Eraser tool. But, in the case of a larger unwanted figure, you have to use the tool in several consecutive sweeps over the figure area, which can still leave some unwanted points that were not carefully swept out. My suggestion is - in these steps: 1. Select a rectangular, or circular or oval (or in the more advanced solution - a free-hand-drawn) area surrounding the unwanted object. 2. Instruct the Eraser tool to sweep over the entire selection area (e.g., "Erase entire selection"), which should take place instantly, thus saving a lot of time in manually moving the tool over/within the area. An added advantage would be that such an automatic deletion of the selected area/object does not accidentally erase more than the contents selected and does not leave any unwanted traces.
