Help button is in top right corner, but all of the tips/tricks/errors appear in the bottom right corner. It took me a while to discover the help "?" button because I had assumed that all help-related information would be in the bottom right.
Also - help only directs you to the overall-help page, it would be nice if upon receiving an error there was a link to a more specific part of the help site relating to the command or action or feature that you experienced the error on. Troubleshooting errors is currently very labor intensive for the user.
