Maybe it would be an idea to let the user customize the SQL-statements. When it comes to WHERE, ORDER BY and LIMIT etc., I think the needs and preferences will be different for each user.
With an embedded database (that I happen to know soon will be introduced with SQLyog 🙂 ) even the number of available statements available from pop-up-menu could be variable. Basically it just takes a two columns -table with columns like 'displayed_as' and 'sql_content'.
It also could be an option of the 'favorites' folder -feature to replace the 'personal folder' that som statements here were availabale from ObjectBrowser pop-up.
You sometimes have a bad habit of hard-coding things!
