17. Turn Drive into a fax machine
Faxes may be annoying, but they remain an unfortunate necessity in many parts of the business world. With a plug-in called HelloFax, you can take the hassle out of the process and let Drive serve as your own personal fax machine.
With the HelloFax Chrome app in place, you just right-click any document from your Drive list to find the option to fax it. The service currently allows for up to 50 free pages per month; beyond that, you can opt to pay for a monthly or annual subscription to increase allowances and gain extra functionality (including the ability to receive faxes through the service using a phone number of your choice).
