Timeline Clip thumbnails

Hi I just installed DR 12 and it looks awesome!
I have a laptop with a 15 inch 1800x3200 display, the timeline clips do not have thumbnails along them, Is there an option for this or is my screen to small for that?

Also it would be really helpful to see the audio waveform in the audio track.

Both options are in the toolbar (right side). The icon looks like a filmstrip. Crack open the manual lately? Sorry had to say it.

I found the option, right next to the zoom slider.
