Is a normal double-click (left mouse button) supposed to do anything? It did in L3, but in A19.1, double-clicking doesn't do anything. For me, any way.
Ben:
Me either. Filed a bug for it.
The normal functionality for this action would be to select the text that your cursor is resting on. I hope that this will be in the final version. Text selection is in general sort of slow and clumsy currently. I'd love to see large improvements as the alpha progresses into beta in this area. Currently, text selection just does not feel like a native function in Logos. Compare with the text selection speed and accuracy found in Page for example.
I'd also love to see an improvement in scroll speed in general especially with larger resources.
Part of the reason that text selection may feel slower than it may actually be is that you get no text cursor when hovering over copy. Also, the selection is not updated as you drag your mouse over the text. Adding these two interactions could resolve much of the concerns with selection. Again compare with Apple's Pages application.
