Since I use auto correct all the time, using Google docs irritates me no end. The first time I write a character's name, e.g. Spell Chick, I then highlight it and make spellchick come out Spell Chick without me having to do anything but type without ever grabbing for that pesky shift key. Since I often mistype George as Goerge, geo comes out George for me.
I hate typing and try to make it as easy as possible. govt comes out government. uni comes out University. All my states and countries automatically capitalize and things like feb come out February. Since I type about rivers in general and rivers in specific, river stays river but rriver turns into River. There are all sorts of way to make auto correct do some of the crap typing stuff.
I use Google docs, but as a storage bin rather than a writing tool.
