Google chrome title bar missing

[joe at actionline.com]

Google chrome has some nice features, but it is also missing some very
important things.  Why is there no title bar?  I frequently use the
window-shade roll-up on windows to hide the contents but keep them visible
(instead of minimizing to the start-panel), but I'm unable to do that with
chrome.

Also, pdf files are not viewable with chrome.

Can't find any fix for that from searching the 'net so hope someone on the
Plug list can explain a fix.
