I'm writing about this because my hosting provider has updated PhpMyAdmin to 4.0.5 only recently.
In PhpMyAdmin 4.0+ (including last development version available as a demo), a bunch of actions are labeled with an image called "theme/dot". this makes PhpMyAdmin's accessibility for blind developers strongly lower. We, as screen reader users, can determine what this or that image does only by its Alt or Title attribute.
Please bring this back somehow.
PhpMyAdmin has always been a really accessible solution, and this (small?) change brought its accessibility down.
