In my project I've marked several files with "do not compile" and "do not 
execute". The infoline in the main window informs me about this several times 
which is ok but becomes very fast uncomfortable, because I start up Netbeans 
with the switch 

-J-Dnetbeans.windows.small_main_window=true

and -fontsize 13

in the ide.cfg.

So when NB wants to show its infos the infoline becomes very long and squeezes 
the menus so that they become hard to read. 

Also when compiling a jar-file NB also shows this information instead of the 
compiling-status so I'm always unshure of what NB is currently doing.

Maybe this type of information is better shown in the output-window.
