How about a third choice: just clear the summary pane (or scroll

The summary pane currently shows what packets are in the capture, so
"clearing the summary pane" and "discarding the packets in the
capture" are inherently the same operation.
Are you suggesting that we change the Wireshark internal model so
that there is no longer one frame data structure for every packet in
the file, or that we, in effect, have *two* forms of filtering of the
display - filtering based on a filter expression and filtering based
on "don't display any packets before this one"?
If so, which packets should, for example, a Save, Save As, or Export
Specified Packets operation see? Should it see the ones "cleared"
from the display?
Neither:
Upon entering some keystroke, literally just do a scroll down so that
only the last frame (being displayed at the time the keystroke is
entered) shows the at the top of the pane.
Can this be done (easily?) (at all?) using QT; I've no idea.
Is this worthwhile ?
Most of the time I wouldn't think this at all useful.
However, if the frames which are being displayed occur at a slow rate,
then "resetting" the screen display as needed now and then might make it
easier to notice when new frames are displayed.
Is this what the OP had in mind ? I'm not sure.
P.S. if the capture display is being done in "no scroll" mode, can a
user hit page down (or something) to scroll down the screen while a
capture is in progress ? (I don't have time to try this right now).
If so, "scroll past" (or something) might be another variant.
