Allow Save Options to be Skipped
Personally, I'd like to skip the extra dialog after I name my file and click the Save button.
If I actually want to alter any of the settings, I'd prefer to do it by actively clicking an [Format] Options button in the Save dialog (opening a new dialog) rather than after already naming the file and clicking the Save button.
Sometimes performance is slow enough that it takes some time for the next dialog to even show, which breaks my workflow as I move on to other tasks in other apps, thinking my file is safely saved already (I did name it and click the Save button after all).
From a UX perspective, once the Save button is clicked/tapped, the file should immediately be written to disk, because that's the intent behind the user activating that button.
