"Scripts can't turn off the status bar."  

If a browser vendor can't trust you enough to let you turn off the  
status bar, I doubt they'll ever trust you enough to let you replace it  
with your own.

A standard <progressmeter> (or <progress>) element might be useful, so  
that non-page progress indication can be more consistent, instead of  
every app developer coming up with their own zany animation. For  
backward compatibility, it could be a container element, like this:

     <progressmeter>(86 %)</progressmeter> Uploaded 46 K of 54 K

A graphical UA would take the "(86 %)", strip out the non-numeric stuff  
(i.e. everything except the "86" and the "%"), recognize it as 0.86,  
and replace the element with a graphical progress meter representing  
that fraction:
     [(((((((():] Uploaded 46 K of 54 K

If such an element is introduced, a <gauge> element should be  
introduced at exactly the same time, so that the Web doesn't fall into  
the same trap Mac OS did when it had one but not the other, and  
developers were confusing people by using progress indicators to  
indicate non-progress fractions (like relevance and quota usage).

     <dd class="uri">http://www.quirksmode.org/dom/webforms2.html</dd>
     <dd>Relevance: <gauge>14 %</gauge></dd>

Which in a graphical UA would produce:

     _Web Forms 2.0 - notes and comments_
         Relevance: [##:::::::::]
