Suggestion for add explorer audio document file option on firechat

Components

FireChat works in addition to Internet connection or cellular phone coverage. Use it anywhere: planes, public transport, cruise ships, campus, and crowd events. You only need some people around you using Fire chat.
If you are not connected to Bluetooth and WiFi networks, you need to "turn on" to send and receive messages (yes, turn on WiFi, even if you do not have internet access). And if you are connected to a cellular network or WiFi access point, then fire chit will work too.So my suggestion here is for the same. I am suggesting options for sending audios,documents and add explorer option.

Proposal

I'm proposing is need of some more options in the chat box should be option available audio, document and explorer on the firechat for the instant send audio file, documents file,

now look without explorer,audio, .doc option

here's just photo upload option

Mockups / Examples

after added explorer,audio, .doc option it's look

I've shown you how it should be implemented in this image. It would be nice and easy to send audio file, document,and explorer file.

Benefits

We know there are most messengers already providing this feature.
Firstly your time will be saved by this feature when you send directly an audio file, document file to your friend.
So more options and more features are needed for the app to do better, It already does allow us to send pictures but audios,document, or even explorer is not possible. So, the proposal clearly indicates at addition of features like sending audio, document,file explorer is important.I would definitely like it to feature in firechat soon.
