Today Dropbox updated their Android app on Google Play to version 2.3.12 which brings few useful and time saving features.
You can now upgrade to Dropbox Pro account which offers you 100GB of cloud storage for $9.99 per month in the app itself without you having to purchase it via their website. Another feature that I personally find very useful is the ability to share files by inviting your specific e-mail contact directly without you having to share the link which was the only option to choose from before this update.
