Great app but needs small tweek

Love the app Work Time, but might I add a suggestion or two.
1. Please make it so I can calculate the hours of 2 jobs combined. Ie working at hospital I need to manage my hours I work in ICU and OR and the combined hours must not exceed a certain amount in a 6 week rotation. I would like to add them combined as well as separately
2. A payday emoticon that can be placed and values entered in.
3. Alert options extended to 1 or 2 days. 4 hours is not enough for a forgotten shift and needing to arrange daycare.

Text me in Paris about WorkTime - Work Schedule, Shift Calendar & Job Manager, v2.3
