The STO gateway is a cool little toy, but right now just a toy. Toss on duty officer missions, exchange, bank and inventory and it could arguably become the coolest tool for a game I've ever seen.
In a way it reminds me of the consoles on or near the captains chair, everything you need at your fingertips. Sometime down the road it would be amazing to see them add in ship auto-navigation with a way to sit on the bridge of our ships (or even better free roam around the ships or sit) while going from place to place. set course from your tablet with sto gateway and then go to the lounge and grab a drink or play some poker do a shipboard doff mission or two and then get a dialog box from your bridge officer or the computer saying you've reached your destination.
I'm not really into roleplaying, but the best games are the ones that really immerse you into the environment and make you part of it, unfortunately this is one of those areas sto doesn't.
