From: Kevin Walzer on
I've released updates to my macsheet
(http://tk-components.sourceforge.net) and windowlist
(http://www.codebykevin.com/opensource/oss.html) open-source Tcl/Tk
extension packages. The macsheet package implements "sheet"-style custom
dialogs for Tk-Cocoa on OS X, while the windowlist package implements a
Mac-standard "window" menu for window management.

Version 1.1 of macsheet fixes a potentially serious UI glitch in which
the sheet window may be incorrectly rendered depending on whether it was
invoked from a menu or a button/keyboard shortcut. The main macsheet
command now includes a "source" parameter to indicate how the command
was invoked.

Version 1.2 of windowlist now offers a complete implementation of the
standard "window" menu on OS X. The package raises and minimizes
windows, and also implements standard keyboard shortcuts for minimizing
(Command-M), hiding (Command-W) and re-opening (click on Dock) the main
window.

Both packages are available under Tcl/Tk's standard BSD-style
open-source license.
