Alarm clock app?

Hello,

This is just an idea that I think would be a nice addition to the Alarm clock app.

I would like to be able to choose a range of days, i.e. Mon-Thur or Mon, Wed and Fri, to have the alarm go off, instead of the present options.

No duh the phone has an alarm clock app already built in! but what is retarded is that you can't choose which days you want the alarm to go off. 

I also find it retarded that you if want your calendar to remind you of an event coming up, you can only choose between being reminded: On time, 10 minutes before, 30 minutes before, or 1 hour before....

Sorry but what if I need to be reminded 20 minutes before? or 15? or 5? or 45?  10-30 minutes is a pretty large jump.

Can we get an update on these apps?
