As a consultant I have to deal with several client's projects, therefore need to see when do I have slots available to accept more projects or not, or if I accept now when can I deliver them. With Liquid Planner I define me as a user that work X amount of time per day of the week, by assigning "Y" time to each task the estimate time to complete the project is calculated automatically and I can give a deliver date to a client.
On top of this we have our own projects and company development projects.
I've tried a long list of project management tools and only see this feature on Liquid Planner.
Are you considering such kind of features?
