Greetings,
When mixing with 4 decks, the layout is not easy on the eyes, especially when songs (waveforms) are loaded to each deck.
Furthermore, When using the extra decks (3 & 4), they do not feed into the Suggestions functionality. Only decks 1 and 2 do.
Also, (and maybe it’s the settings on my computer) when I pull the bottom right corner to fill the enter screen, the search section on the bottom is cut off. If I switch to the search view, the size of the window changes. It does NOT do this in two deck view.
