Google does many things right, but not these

1. The latest version of Google Docs appears to have removed the ability to add words to the spell-check dictionary.
   
   
2. The Google Docs spreadsheet doesn't have a simple way of displaying just the month and year of a date. You can write a formula that will do that, but Excel allows you to specify custom display fields easily.
3. Google Chrome doesn't allow you to use multiple Google accounts for email and other apps. Firefox has a nifty extension, called GMail Manager that monitors as many GMail accounts as you want, including those in different Google domains.
   There are reports that Google is rolling out a feature that allows you to log in to multiple Google domains and keep those logins active simultaneously. See Google Tests Multiple Accounts Sign in. I've not seen that feature in my account(s) yet.
