haha.  I just can't help making more trouble for myself with nifty ideas.  I think there were crazier ideas in my initial pitch back in April, here's my abstract:
Keeping track of past experiences to assist the user effectively manage the MySQL database server using phpMyAdmin web interface. If a user selects a certain database as he first logs in to the system, this user preference will be performed automatically after the script intelligently decides that this is user's preferred destination. Users will have options to change the automated settings if they wish to. A set number of these automated configurations will be designed to assist the user.
Sounds really interesting. ;)

Please give an example where this override would be needed.
I think I was confusing it with something else. 

Here are my notes on the code that I have written so far:

- I have commented out user settings interface for "Default Language" as only one of the languages show up in the drop down menu.  And when I hit submit that language is set to default for some weird reasons.

- The current value of a setting will be selected on page load in drop down menu element, and it will be printed in text box input.  The mechanism is a bit confusing, and I will work on it first thing tomorrow morning.  Any suggestions to deal with this problem differently?

- need to define an additional method in sql driver class to select all of the settings' values at once

- need to implement a sophisticated interface to handle errors

- SQL query still does not produce expected result. I am wondering I need to link queries with server, but I was not able to figure out how to extract link to connection server.

- I see that some of the configuration settings can simple be changed through ./libraries/config.default.php such as PropertiesIconic.  I am wondering that these settings are directly extracted from config file.  So, in this case, may be create a new config file to set these settings.

Thanks!

P.S. Please bear with me if there is a confusion.  I don't drink coffee, or coke to keep myself awake.  I am an all-time water drinker.

These configs will have to stay there )in the config.default.php +
config.inc.php) because the userprefs feature might be not available.

IMO, as the parameters chosen to be part of userprefs should not have an
impact on security or performance, the value set by each user will
override the one set in the general config file.

This will have to be tested when we have an implementation prototype to
test.

Here, username is a column name and root is ... a column name?

Same question. I think you forgot to quote the constant you are using.

Use $GLOBALS['cfg']['Server']['pmadb'].
