When retrieving a call from park, I have to click the little handset icon for the Pickup Call popup to appear.
It is a little hard to hit this icon sometimes cause it's small. Better would be if the whole line from left to right including the part containing name and number of parked party would be clickable.

Just like it is with calls in queue. There I can click the whole line.

Convenient would also be if several parked calls would be distinguished from each other slightly via a different colored background fond. E.g blue and a little darker blue.
