Slow updates, missing features

Starting to feel like the developers are either being bought out or they are going to close up shop. The updates are lame and come out every TWO months! Pretty sure its being abandoned. Never the less, Id like them to add:

1. More unique sounds to choose from for notifications.

2. The banner notification reply should be a quick reply (like iMessage) instead of kicking into the app. Spark does this beautifully and this feature is keeping me from switching.

3. Id like an option to treat messages that have multiple emails like other apps do and thread them into a conversation view instead of treating them as individual, itemized emails within a thread.
