1. Work-life balance can take a hit at times during tight deadlines.

2. Salary can be increased a little bit more to be at par with Google and Facebook to prevent some employees from leaving for those companies.

3. Nothing else really.

The company should start focusing more on future technology trends and use all the really smart people and talent to come out with something really innovative that people will love. Time to market delivery should be improved greatly so that we don't fall behind other companies and we can be the market leader again.
