If I open a file with lot of instances
On any instance hovering the mouse over the port name of an instance should display the instance name, reference module and whether the port is input/output of the instance. Usually the instances are big and the context is lost. If the port is output then click on the port should navigate to the driver in that module. If its an input then a click on the port should navigate to the file and highlight all the uses.
On hovering the mouse over the signal connected to the port should highlight the driver instance and consumers. Clicking on drivers should take to driver instance port. Clicking on any consumer should take me to the consumer instance port.
