The standard
Wait for User Action action goes the other way (it stops the workflow), so there isn't anything handy that has a built-in counter. You can fake one with a
Run AppleScript action though, by popping up dialogs with short timeouts, for example:
<pre style="
font-family: Monaco, 'Courier New', Courier, monospace;
font-size: 10px;
margin: 0px;
padding: 5px;
border: 1px solid #000000;
width: 720px;
color: #000000;
background-color: #FFEE80;
overflow: auto;"
title="this text can be pasted into an Automator 'Run AppleScript' action">
on run {input, parameters} -- countdown dialog
set WaitTime to 10 -- this is the overall time to wait
set Interval to 1 -- this is the interval between dialogs
repeat with Timer from WaitTime to 1 by -Interval
if Timer ≤ Interval then set Interval to Timer
set DialogResult to display dialog return & "Bento will close in " & Timer & ¬
" seconds..." buttons {"Cancel", "OK"} default button "OK" giving up after Interval
if (button returned of DialogResult) is "OK" then exit repeat
end repeat
return input
end run
</pre>
