Please consider including Collaborators in Workload View. Collaborators do not not need Workload View, but if they can be assigned tasks they should be available in the Workload View. Right now those tasks just disappear from the view.
Not having our Collaborators in this view makes planning very difficult for our teams. Our Collaborators are our field people that fly all over the world and are shared resources for our Project Managers. We use tasks mostly to tell them where they need to be. We want to be able to see them in the Workload View so we can make sure we do not have them scheduled to be in two locations at once (ie. Egypt and Paris at two different job-sites).
The option of having to purchase user licences for this limited functionality (they do not use Wrike for anything else) is an expensive proposition and I think ultimately will make us reconsider using Wrike.
We were also thinking about using Wrike to keep track of some pieces of equipment that we move from jobsite to jobsite. These are a different kind of resource but if we could make the equipment Collaborators we could track its location and not double book it...if we could see it in Workload View.
In short, it is a bad design to be able to assign tasks to Collaborators but not be able to track those tasks in Workload View.
