dragging the timeline horizontally by press spacebar

I do see that pressing and holding spacebar in AE doesn't start playback. I'll see if we can match that behavior.

BTW, Page Up and Page Down also work to page the timeline.

Thanks for your feedback.
It could work the way as in AE: Threr you can drag the time line by SPACE + MousebuttonDown AND you can start the playback (without mousedown)
For me thst whould waork perfectly and it would be more constistent between the two programs.

Because we use spacebar to start playback, we can't use it to pan the timeline. We do have timeline panning though.

On a trackpad, you can use the two finger gesture for horizontal scrolling/panning. Shift + mousewheel will also pan the timeline.

We use opt/alt to pan the scene panel, we could look into doing that for more fine control.
