Components
Hatke Messenger is an SMS Application created as a task for the quiet Android Developer Developers. Github

Proposal
I would like to suggest some additional features, as:
Add recipient, and
Forward message
Mockups / Examples
Here is an example of adding features that I recommend.
this is an example of the recipient feature i mean 
the forward message example I meant below 
Benefits
Recipient is a user auxiliary feature to add the contacts we want to send messages to. The contacts we have saved will come out when we search for them
When there is an important message coming in and we want to send it to someone else, we can take it by pressing forward to send it to the person without having to retype.
