Anyone else agrees or supports these Calendar suggested features for Smartermail?

I am for copying the functionality of emClient as that seems to be the absolute most compatible program with SmarterMail (that I've found). It allows setting the default duration and reminder time. I would think having those two at a minimum would be good. Additionally, I would love to see the category, email notification, conference room, availability, and private appointment as user definable options. This way you can have the defaults in. 

Although attendees, time zone, all day appointment, location, and recurrence could be added as defaults I don't see them being good as they can change often.
