Saving conversion settings?

I'm not sure where to post feature requests, please advise if this should be elsewhere.

I love Calibre, now one of my most-used programs! Thank you!

I convert a lot of books and each time have to enter the same settings. Is there a way to save the settings? For example, I change the base font size, font size key, minimum line height, justification, margin sizes, and prevent rescaling of cover, using same settings on all books, at least initially.

Is there some way to capture those settings? If not, would you please consider adding it?

Also, I find it difficult to keep track of which books I've just added as soon as I do anything to update the list so they're no longer at the top of the list, unsorted. Is there a field for this I'm overlooking?

Thank you for Calibre!
