Some love for new Circle Selection

I use the new Circle Selection as a Paint Selection. The problem is that unlike the old version of this tool, I cannot quickly change the radius of a circle. And by default, it is big enough. I would like to see a hotkey for a quick change of the radius and a global setting of the initial size of the circle (so as not to reduce it every time)

Using an old tool that blocks navigation is not an option for most, I think.
