Implementing this is clearly beyond my skill set, so I can do little to
make this happen. However, if this will NOT happen by the 0.9.14
release (or even in the more immediate future), I'd like to suggest
that the changes I mentioned should be implemented to improve the
current situation. At the very least, I think the trivial change to cap
auto-resiize width should be added.

Those can probably be fixed, but here are some problems with auto-resize
that might be inherent in auto-resizing:
It requires Ethereal to generate, for every column to be
auto-resized (not all columns are auto-resized) whose maximum
size can't just be computed from the maximum numerical value for
the column, the text for that column, for every packet. Right
now, the GTK+ widget we use requires Ethereal to compute the
text for every column, but (with some changes, e.g. support for
fast random access to packets in a gzipped file, which should,
according to somebody I talked to, be doable if we save copies
of the compression dictionary values at various points in the
file) I'd like to use widgets that call back to the Ethereal
code to get column text, and not generate that text. This would
save a significant amount of CPU time and memory.
It requires Ethereal to compute, for those columns, the pixel
width of the column values for each row. At least as I infer
from this note from a message by Olivier Abad:
- the CList widget in gtk2 is slower, probably because gtk2 uses pango
to display text (various messages on gtk-app-devel confirm this)
that's more expensive in GTK2 than in GTK1. (Unfortunately,
this *other* note:
- the ListStore/TreeView replacement is painfully slow (also confirmed
by gtk-app-devel archives).
indicates that the obvious widget to use, in GTK2, for the
previous paragraph's problem is slow. I just hope widgets such
as Cocoa's NSTableView, QT's QListView, and so on are reasonably
efficient if you have hundreds of thousands, or more, rows....)
