What effects do choices in Wings of Liberty have in Heart of the Swarm?

As per my other question, I know that choices made in Wings of Liberty affect (at minimum) dialog in Heart of the Swarm.

What other effects do these past choices have on the campaign, if any? Are there any other choices that get carried through?

Solution 2:

It seems like the dialogs in HOTS are an aftermath of some of the choices you made in WOL. I am not 100% sure, though, since I'm only about to finish my first playthrough.

Note the dialog with Nova mid game; for example, the dialog with Izsha about the Terran having an airs uperiority on Char. Based on my WOL, it matches the choices I made in my last playthrough of WOL: nova missions / Tosch mission and No Nydus / No air
