A minor suggestion, and am unsure if it is possible.
In the 'Log Task time' dialog, in the 'When' Time drop down, there are a lot of times presented in half-hour increments. Would there be any way to get this to only present working hours, or at least pre-scroll so all working hours are shown (i.e. perhaps scrolled so 7am is visible at the top of the drop-down - could scroll up if anything earlier is needed)?
It would save a bit of scrolling when adding task times for items in the afternoon. I personally would never use time before 7am.
