Browser-Ice,
When you say "task view" I assume you mean the Gantt Chart view and yes you can do a split screen. If you are interested in dependencies associated with a specific task I suggest you use the Relationship Diagram in the lower pane. When you select a task in the upper pane (Gantt Chart), the Relationship Diagram will show all dependencies for that task.
You might also try the Task Path feature found under, Gantt Chart Format > Bar Styles
Or, the Inspect feature found under, Task > Tasks
Or, a custom filter using a Flag field to isolate desired tasks.
Lots of choices.
