But, you can display the toolbar in "View", "toolbars". I had to do this a couple of times, turning it off and on so I could see it -- I have 2 monitors.

I've seen this author's utilities, both in RoundCorner and other toolsets that have regular SketchUp-like tools. Why don't I get them?

Found the Toolbar! All is good now!

I am a Sketchup beginner. I just viewed the Fredo6 video on how to install the Library first, then the Roundcorner plug in. What I got was not what I expected. The video showed nice Sketchup-like tools -- in the video's example his version of Scale was used. What I got was a rather large and not as well formatted box for rounding corners -- it looks like it was written in the 80's. I'm using Sketchup 2015. How do I get the nicer Sketchup-like tools?
