Obvious post is obvious. But if one person has an 'eureka' moment it's worth it.
Sometimes I find reading text here or scrolling through a dashboard uncomfortable, because they're too big (not a criticism, since solution is staggeringly simple). Changing that takes only a few button presses . You can freely manipulate level of zoom on your page. Any page in an internet browser. Not just on booklikes (works for firefox, can't speak for other browsers)
"ctrl" + "-" -> zoom out
"ctrl" + "+" -> zoom in
Repeat until satisfied.
You may want to use that on dashboard or just while reading reviews. I know it's obvious, but sometimes people need to be reminded of existing options.
