[dev nov 8] I often find that the "Go To Class" dialog (Alt-Sh-O) is
much narrower than it ought to be. E.g. while working on the
minicomposer API example, I open the dialog and type "Sampled". This
narrows it down to:

org.netbeans.examples.modules.minicomposer.Sa....
org.netbeans.examples.modules.minicomposer.Sa....
org.netbeans.examples.modules.minicomposer.Sa....

Of course it is possible to scroll right using the mouse, or by
pressing Tab and then Right, but this is inconvenient; it is a very
common operation to use Fast Open, and normally you just want to type
the letters of the class name, and use Up/Down to select. If you Tab
into it you can use Up/Down to select but you also have to Sh-Tab to
type more letters.

It would be nicer if the dialog were simply wider, in which case most
class names with package would fit, without needing to scroll. And/or
make the dialog automatically scroll to the right when typing letters;
generally you can find the class you want by the the class name and
the last component or two of the package name, anyway; prefixes such
as "org." or "java." are not very useful in distinguishing classes.
