Google Drive

There were some aplications for Google Drive i saw that looked like they could be helpful.
1. Floorplanner
It's pretty self explanatory, what it does. But its a neat concept nevertheless if you even need to see the layout of a room or design a room or something.  

2. Hellosign
another interesting concept, and green too! you can sign documents, checks and stuff, request signatures, and save templates of documents to reuse.

3. Zoho writer
Its like Microsoft for Google drive. Based on costumer comments it sounds like it has a few issues that need ironed out however, like spell-check not being an automatic feature.
