These are nits about the disk icon on the Editor's toolbar:
the tool tip says simply "Save" but it should say what it's actually going to do ("Save As" or "Save Directly")
currently the icon activates the Save As (opens dialog) menu choice, but this is antithetical to the idea of the toolbar icon, which should be "do the most automatic thing possible to make my life easier". So, the disk button on the toolbar should activate "save directly using preferences" option
The use-case for me here is:
select a screenshot area and open in editor
add an arrow or a box
save with defaults
This needs to be efficient and streamlined when you're taking 100's of shots for a manual.
