Nope, the lens setting did not work. I set the new lens for the way I want things and saved it.
I closed Sonar, reopened it, and it opened with the lens I created but the VSTi plugins were once again set to "Sort by Category". I even toggled the lens off and then back to the one I created, but the plugins list stayed the same.
It seems the only way I can do it is change the plugins default settings each time I start Sonar.
I also looked in the Preferences to see if I can change the default view of the VSTi Plugins, but couldn't find anything.
