Resource Management already has a great view on the Schedule tab to see if someone is over allocated but unless you have licenses for every user in Smartsheet only Management can use this tool. I would like to create a view/report per individual that looks the same as in the Resource Management Schedule tab and place it on each individuals Dashboard in Smartsheet. Individuals constantly get pulled from one project to another and have to change their start and end dates in Smartsheet's Project Schedule but they can make a change and it overlapps with a different project and don't see the problem without doing some digging. This view makes it very easy to see if they are over allocated so they can take the correct measures with management to re-schedule.
This could also help with a view for Portfolio Management in Smartsheet
