To which the answer is "no, no it's not".
You may be experiencing some problems with alt focus, I just had this explained to me by Dyntehos which was much easier to understand than the previous person who tried who basically said "It's broken!" and when I asked "How?" stormed out of irc.
Take this example:
You have your mothership selected, you are in the sensors manager.
You alt focus on the enemy mothership.
You hit f to focus on it.
It focuses on your mothership, you get annoyed.
The problem here is that there is no need at all to hit f, I have no idea why people are doing it but it must be a habit brought over from homeworld 1. All you need to do is alt focus, you're now focused on that ship, no need to focus again!
Some of the differences from homeworld 1:
Alt focusing does not zoom you all the way in on the ship.
Alt focusing does not bring you out of the sensors manager.
You'll find both of these are necessary to effectively use the sensors manager, it's not just a map like in homeworld 1, you can play the game from the sensors if you want.
