Would it be possible to be able zoom/pan using the trackpad please?
Thanks for the request! Don't hold your breath (right now for technical reasons we're limited to specific zoom scale factors), but this is a good feature that we know is wanted!
many thanks Jonathan for the reply, perhaps just some hotkeys would suffice for now?
You can use command-minus and command-plus to zoom in and out; command-zero will go back to 100%.(note this changed in v3.5; it used to be the greater-than/less-than arrows)
Many thanks Jonathan!
