Nice Email App But Needs More Improvement

This email app is very promising and a good tool for productivity. Following are just some of the cons:
1. Email is quite slow to load
2. No portrait mode
3. You cant choose which folders to display by default
4. Your signature will always double space when you compose an email
5. Email Aliasing is not present

Looking forward to the developers for further enhancement and improve performance.
