Low Memory Chat 

Have you actually done CPU profiling of both? Last time I looked at your mod...it was calling somewhat-expensive functions (this:GetParent():GetName() twice) during a non-throttled OnUpdate function (for a "module" I didn't even have "enabled") which was causing constant CPU usage, even when nothing was happening.

Your mod also creates a copy of the global table 7 times during startup (and then proceeds to use getglobal instead of the cache). Your other "modules" create an astonishing amount of garbage as well, not to mention timestamps creating some very vauge and unneeded global functions.

By all means correct me if I'm wrong, but I don't think you've done as extensive profiling of your own mod as you would want your users to believe, and your mod is far from efficient in relation to how you advertise it.

feature needed: option to popup message if chat frame contains your name

Why not use PhanxChat ?

This addon is about perfect..I can't think of anything else to add.

edit: I can't get my chat channels name's shortened

Thanks jaliborc! This one gets better from version to version... Keep it up !

wtb officer channel sticky.

..and the menu button inside the chatframe. Exactly like the scrolldown button but in the upperright corner.

Greetings disiz

does the officer channel sticky?

Having chat fade disabled by default would be excellent to have.

Not true. There's nothing wrong with using XML. The rest of your post is... not wrong enough to warrant correcting, but some of your generalizations show how generalizations are bad.

Just for reference: http://www.wowwiki.com/UI_Best_Practices

* Globals are bad
* Reusable Tables inside loops are generally bad
* Global-environment tables inside loops are _always really_ bad
* Re-skinning a single frame 7 times is also bad
* Creating the same function 7 times is bad
* Doing the same *anything* 7 times in a row is generally bad
* XML is unneeded (and bad)
* Efficient use of conditionals statements, not so bad!

And for good measure:
* Improper indentation is bad

(If its any consolation, I'm honestly trying to help here, albeit through criticism :P)

It is unnecessary to create the backdrop and region tables and the scroll and hide local functions 7 times. This practice increases your memory use. In fact, you don't even need to create the region table-- l2varag. Also, having your scroll function as a global is just asking for trouble.
