no taskbar icon ... (or some other things) .. see Tk::Wm  perl -MTk -e " tkinit()->overrideredirect(1); MainLoop; "

not sure where i learned it, probably from tk splashscreen or maybe reading Tk::Wm and trying everything :) 

$mw->overrideredirect(1);
$heightwin ->overrideredirect(1);
...
$mw->overrideredirect(0); ## 1
#~ 2 3 4 2 3 4 
$mw->deiconify;
$mw->geometry('+0+0');
$mw->raise;
$mw->state('zoomed');
MainLoop;

It's also pretty slow. It takes about 3 or 4 seconds for 500 rows. I'm thinking about how to speed it up but I'm not sure.

you can always throw up a splashscreen :) but ~3 seconds is reasonable for me, half of that is loading/perl/tk... the other half is the dlineinfo loop ..

If you were to startup spreadsheet program or browser its not significantly faster

You could use dline/bbox on first line, and then guesstimate the width/height for the rest of the lines, but that only probably shaves at most half of ~1.5 seconds (not really sure which part of the dline/matrix equation takes the time, not gonna timeit)
