Almost there, but not quite. The "Wide Window" (A.K.A flatbed or multi-column) only exist within the catergory folder you're visting.
Like within cakewalk: You get the single category list, showcasing all your FX folders (in the FX Bin view) with the arrow next to it. Once you hover or click on it - it opens another single (narrow) page, where you have to click 20 times to get to your "favorite/favourite" (depend on where in the world you are) plugin. This is where the wide window will live.
This is as clear as I can get with this. Been explaining the same thing over and over.
And like I've said many times before on this topic: You will have the option to switch to this feature, like with the other 3 available features. Adding this to that wont break the daw as what people seems to think.
