We need the ability to create recurring tasks and events, especially for Projects. Example - We run a digital marketing agency. A Project for us might be providing a Search Engine Marketing solution to a client. Part of the Project will require weekly AdWords Optimization, weekly content development, etc... These tasks need to be assigned to the right person every week. Having to rely on someone to enter them every week is inefficient and counterproductive to the "Zero Input" concept of ProsperWorks. Not to mention the issues that can arise when someone does forget to recreate a task.
It has been recommended that we create a task once and instead of marking it complete we just change the date on it. This is NOT a solution. Each time a task is performed we need to record notes as to what was done and tie them to the date they were completed. Hence we can't just change the date of a task ongoing.
I believe this type of functionality applies to many industries and hope this feature makes its way on to your development roadmap sooner than later.
