From the main page, follow the Databases tab. At the bottom of the listing of databases is an icon with the text Drop. Those should be improved so that when hovering over it, the mouse cursor changes to show it's a link. Currently it just stays as a pointer which is not ideal UI behavior.
I have created a pull requst https://github.com/phpmyadmin/phpmyadmin/pull/1009
Please check this pull request too (includes fix for checkall link also ): https://github.com/phpmyadmin/phpmyadmin/pull/1012
Would not be better if it would behave like a button?
Like this:

"Check All" as link and "Drop" as button?
Implemented with https://github.com/phpmyadmin/phpmyadmin/pull/1012.
