When you use planner (as well as all other project planners ) the tasks 
and other inputs e.g lags, usually work in weeks, days or hour 
resolutions. 
 
It would be good to allow for special projects (which I call missions) 
that are simply on a smaller time scale than projects i.e. minutes or 
second resolutions. 
 
Where do you use these you may ask ? Simple ! Anything from, 
 
- Planning parties (7pm people start to arrive etc etc...), 
- Planning trade shows (show open, product demos every 15 minutes etc), 
- Planning presentations (especially multi-speakers with 5 minute talk - 
slots, 
- Planning a school day-trips (08:00 bus arrives, 08:15 bus leaves 
etc...) 
 
 
Nothing really is different from a project EXCEPT that Planner should 
assume hours instead of weeks, minutes instead of days and seconds 
instead of minutes. 
 
Could even work the other way too with say a concept of Campaigns where 
it defaults to Months, Weeks and Days as the main time periods. That 
could be useful if say you're planning ... 
 
- Your School year or degree, 
- A brand awareness campaign, 
- Documenting a historical reenactment of a military campaign, 
 
Thoughts ? I feel it would be a nice enhancement thats would not be too 
hard to implement.
