The ability for each document saved within our account - as well in general- it is able keep track/history etc over many years (20+). And best part would be we can access these documents from any device using an internet connection anywhere or if need so offline too via wifi! As said earlier, all information kept intact which helps us later when looking up certain details / historical facts related to information provided by users at some time and date range previously recorded through doco! I like that it is easy to use, even for those who are not familiar with word processing software. It has been very helpful in my work as an online tutor; I can quickly create lesson plans using this software. The only downside I have found so far is that there doesn't seem to be any way to export files from the program into other programs (such as Microsoft Word). For me, I've used docXonomy to organize all of my teaching materials.
