just a question though. wont it be possible shipping phpmyadmin with "arctic ocean" as a default theme? the origional theme is kinda boring etc.. no offence. the other default setting would be the $cfg['DefaultTabTable'] = 'sql.php'; as most of the hosting companies dont bother changing the phpmyadmin instalation.
maybe bring in a "temp" selection. on the home page have a drop down box where the user selects what clicking on the table name on the left frame should show. this writes a cookie. if the cookie isnt found it uses the default of "DefaultTabTable"
