Default number of days for reply Rated 4 out of 5 stars

I just installed this add-on, and it seems to work great, thank you for the work, and for sharing!

I'd like to suggest something though: Would it be possible to allow users to set a default number of days to calculate the date for the expected reply? I'd like to set it to 2 or 3 by default. Well, that's a "nice to have" feature, certainly not crucial. Thanks again for the great tool.

This review is for a previous version of the add-on (0.5).
