If you have words, excels, power points. etc. document and have been tabbing back and forth between a myriad of browser windows, it makes you feel annoy and angry. Get this program. And If you use Microsoft Office 365 on your Mac all day long, I think this is the program for you. Why I would evaluate it like that, because I have using this app for a long time and I know its merits. I did find All Docs app for editing my documents, such as Word, Excel, Power point, and the convenience of having my files in cloud and hard drive. All Docs app quitely download my documents in background. Whether I'm editing an existing document or create new one, All Docs keep sync to my hard drive whenever a change detected. It is stable, organized and productivity way to live, save me so much time, and for that reason I give it 5 stars. All in all, it is wonderful program, the sync files function work flawlessly, and the notifications work very well. Now I use it anytime and anywhere, there is no any trouble during it works. And hope it have more improvement in next update.
