I used to use mytop but since 2 years or so, I use innotop now, which is just like mytop but with more features geared towards InnoDB tables:
http://innotop.sourceforge.net/
It also works pretty much the same as mytop for MyIsam tables, I use innotop in such away on one of the sites I own.
I use it too.. My "top" arsenal is composed of top, atop (for apache) and innotop.
check out htop
Now I want to write toptop, which measures the hit your system takes when running 4 different kinds of top. :)
Very true, specially monitoring the monitors :)
I used this ages ago, but it became less and less usable as MySQL advanced and mytop didn't.
Unfortunately I don't see MySQL 5.x as being supported.
Sounds like you've discovered what that "fork" button is for.
