I am with Sarah here! Start dates and other options would be great. They should let you customize this list. It is preventing the same basic functionality the is available today in the My Work screen. Huge set back without this function.
The ability to set predecessors for issues or cross objects like tasks. Being able to set a predecessor between issues for items such as "unplanned work". Would also be nice to create cross object predecessors such as a task being a predecessor for an issue to begin.
Pull the custom forms from the recycle bin when they are accidentally deleted. This has happened far too often with clients and it would save everyone a heart attack :-)
