The problem with putting vendor names first is that the plugin name can be longer than the width of the fx bin. For example, FabFilter does that and the first 19 characters of every product name is the same, e.g. "FabFilter Pro-". On some DAWs, you might see an effects chain where multiple plugins cannot be distinguished from one another. SONAR lets you rename plugins via the Plugin Manager, but not all DAWs do.
One way to organize plugins by vendor is to install them in a separate folder. For example, I keep all 26 of my iZotope plugins in c:\program files\cakewalk\vstplugins\izotope. I am running 8.5, so iZotope appears as a submenu in the VST selection context menu. Does the current version of SONAR not still do that, even though plugins are now selected via a dialog?
