WHY? 2-deck expanded library view: no BPM / sync option vs. 4-deck same view mode: yes

In 2-deck mode / no waveforms (=expanded library view), there is no BPM indication, no sync option for the decks, while in 4-deck mode / no waveforms, there is.

Why. I use 2-deck view and prefer expanded library view, loss of waveform-view doesn’t bother me that much. BUT I would smile a lot more if I had the same BPM / sync options as in 4-deck mode.

Can you please explain why or, even beter, solve this inconsistency?
