I keep my books as EPUBs, but auto-convert them to AZW3 when I copy them to my Kindle, and then delete the AZW3s so that if I have to fix anything, I won't end up editing the EPUB and then accidentally uploading the old unchanged AZW3 to the Kindle.

I've recently had to change a few conversion settings, and each change has meant spending about three days reconverting all my books to make sure the new settings "take" -- because if not, and I edit an EPUB and then upload it to the Kindle, it uses the saved conversion settings by default.

When I convert multiple books manually, I can uncheck the "Use saved conversion settings". When I convert a single book, I don't have this option (why not?) -- I can go through all the settings and make sure they're correct before converting, but I find it easier to pick another book and convert the two together so I can uncheck "Use saved conversion settings".

However, for autoconverting (when auto-adding, or saving to a device) it will always use the saved conversion settings. Which is why, after changing a setting, I have to spend three days converting everything again -- otherwise I'll edit the EPUBs for the books I'm proofing on the Kindle, and when I upload them again they'll be converted using the old settings. (And it's easier for me than trawling around on the Kindle to find books I've started looking at and then put down because something else has come along, and converting just those books.)

I've never found a situation where, after changing some conversion setting, I want to ignore the changes I just made and use the old settings instead -- I always want the new settings (that's why I changed them!). And even if a specific book needs unusual settings, I would have thought that would be the exception rather than the rule, and a per-book preference would make more sense in such a case.

Wouldn't it make more sense for "Use saved conversion settings" to be unchecked by default? Or at least have a tweak where you can specify the default setting?
