Home page Grid View- customization updating

You can also double click any of the projects on the home page and add in priority there, would that work?

Regarding priortizing by adding a organization custom field - would I be able to use the new field in order to sort or select all prioritized tasks in a report?, I assume this feild will be displayable only in a customized view.

regarding the double click any of the projects on the home page and add in priority there,- I was not able to do this- I am able to update the project priority by the right mouse button - selecting properties and within the properties to update the priority.

How can all projects be sorted by priority ?

How can the priority of the projects be displayed on the HOME Page?

There isn't a way to display priority on the home page, the best way to do it would be in work items. I have put in a feature request for you though! As for the double click, I mean this as a way to quickly access properties (instead of right clicking). You can double click any icon to open up its properties.

My home screen only shows a single icon, the parent directory. I would like this home page to show an icon for each of the projects for which I am Project Manager. Despite having the drop down boxes at Projects in the Works and I am the Project Manager it still only shows a single icon for the parent directory.

You always see the top most project on your dashboard. If you want to see the sub projects there, you need to breakdown the master-sub project structure and that way you will see each project as stand alone.
