Just want to +1 this same request, or +100 if I could... How many times have I waited for a large complicated PDF export to complete, opened it and groaned as I see it's used the default All Spreads layout because yet again I didn't remember that I have to manually change it every darn time!! Or even the "Current Page" option - when exporting PDF multiple times to iron out issues on a given page this gets incredibly annoying. It just needs to remember the last used value, even if just for after the first time it's used after the app is open. It remembers the last used export file type and export preset OK, why not this simple layout option?
