---------------------------------------------

> Should we make the limit configurable? 

We can, but do you really need it to be configurable? It will be yet another 
knob to turn for the user.

> good if the original job name will be displayed as an alt-text.

sounds like an excellent idea. are you saying that if the user hovers the mouse 
above the jobname, then the full name of the job show up?

> Limit Job name on jobtracker.jsp to be 80 char long

> Sometimes a user submits a job with a very long job name. That made 
> jobtracker.jsp very hard to read.
> We should limit the size of the job name. User can see the full name when 
> they click on the job.
