(Archived) Add tooltip to the icons

[abdu 19]

Most of the icons are familiar if you use any word processor. I thought the one with the checkmark was to spellcheck the text. It's for adding a checkbox. It makes sense to add a tooltip explaining what the icon does when hovering on the icon.

+1.  Also, it should be possible to make the explanatory text on the reminder, share, etc buttons go away.  It's quite a bit of clutter, and an option to reduce it would be useful.  Better yet, kill the text and use tooltips here too.
