Hi Tj99,
I see your point, but I would be happy with just the plugin names on each tab like in S1. Of course, it would be nice if Cubase added plugin aliasing (renaming) so that the names displayed were easier to identify.
I’m not saying I am against your idea of screenshots on the tabs, but it wouldn’t be a priority for me. Again, I may confusing your original post (500 series rack) with the idea of a tabbed VST window (like S1). They are two different ideas in my mind, but maybe you are looking for some combination of the two ideas. The tabbed VST window idea could leverage the existing GUIs of each plugin where the 500 series rack would need GUIs to be customized to be usable, in my opinion. Just a simple screenshot of the GUI downsized would likely be too small to be of any real use to me personally.
Maybe if you mock up the idea and post a screenshot, it may click as to what you really want it to look like.
