Change size of the Remove Tool

My question is short and simple:

Is it possible to change the size of the Remove Tool the same way as the brush or the stamp tool in the picture by clicking the right mouse button so I dont have to move the mouse away out of the picture? Because so far the only way changing the size ist above in the menubar.

Are there plans to assimilate the Remove Tool with the Bruch or the Stamp Tool? It is pretty awkward that way and it would speed up the whole process.

Thanx
