<div class=""><font size="3" face="Calibri" class="">This approach looks great, but I still say it can
be achieved with non-overlapping windows. Yes, allow lots of windows. But also
allow the user to design and save bespoke non-overlapping layouts which suit her

If all you did was expand a few, you had effectively non-overlapping windows, (or panes). But then you could yank them out, so each one was a whole window, or stick them back into a column of entities only related by you.

<div class=""><font size="3" face="Calibri" class="">I first encountered APL when searching through
wastebaskets in room 404 (!) of the Electrical Engineering building at Imperial
College, London, for poorly overprinted passwords. It was initially
indecipherable, since there were no keywords. So I’d enjoy posting my source

programmers. :)</font></div></div></div></div></div></div></div></blockquote><div class=""><br class=""></div><div class="">Let them eat glyphs! :)</div><br class=""><blockquote type="cite" class=""><div class=""><div style="WORD-WRAP: break-word; -webkit-nbsp-mode: space" dir="ltr" class=""><div dir="ltr" class=""><div style="font-size: 12pt; font-family: Calibri;" class=""><div style="font-size: small; text-decoration: none; font-family: Calibri; font-weight: normal; font-style: normal; display: inline;" class=""><div style="FONT: 10pt tahoma" class="">
