At first, sorry for my bad english!

I really like Inkscape and working with Inkscape is really nice, but there is one thing I don't really get in my head.
How I can adjust a max. Distance for the knots / node? I mean, for example when I create a logo, it always have some ugly "dents"...
Just a simple example, I wish to create this logo:

If I made this with this tool


Cause I can't observe all knots / node it always have some "dents", coz my logos are complex

So, is their a way that I could fix the "dents", i hope their is tool that reduce or expand the Distance of the knots / node to chosen maximum???
I hope you understand what I want to say....
