When starting from the Taskboard it takes minimum 3 clicks to create the first new task (Backlog item menu -> Add Task -> Save (& xx)). The consequent tasks can be created with one click when using Save&New in the form, however the Taskboard is not fully visible anymore.

As as user I want to create a task directly on the Taskboard (with one click) so I can do this quickly and I do not need to switch the focus from the Taskboard to other windows.

Maybe it would be nice to implement on the Taskboard something similar to how the Portfolio Items are created on new Roadmaps (using inline "+" button). The same idea can be applied for the other boards (Storyboard, Testboard).
