Appetizer 1.2 (Version 1.2.3 released)
Application: Appetizer
Category: Dock application
Description: Appetizer
is an application launcher for PortableApps applications. Rather than
organizing the apps as a list like the Windows Start menu, they are
organized in a dock a bit similar to the Mac OS X dock bar.
Release notes: This is an early release of
Appetizer v1.2. There are still several bugs to fix, but the app should
be stable enough for testing. The two main new features in this release
are:
* Plugins
The app now embeds a lightweight plugin system based on Lua. This
will mainly allows adding new features without having to bloat the core
executable. For now, there's just one plugin: "Add to group on
right-click", which allows adding an icon to a group from the context
menu. In this release, there's also a "test unit" plugin, which can be
used for testing. Creating plugins is relatively easy as there's only
one script file to create. It's possible to hook into the app by
creating event listeners, and to create new Appetizer objects
(shortcuts, popup menus, option buttons, etc.). I'll post the API doc
on the website later on.
* Killing applications
There is now an option to kill the applications that are locking the
drive before ejecting it (in "Configuration" - "Operations"). I'd
appreciate if you could give it a try to see if it's working on your
system and if it manages to kill all the apps. Obviously, the
functionality uses some low level system calls so I don't know how well
it would work on different systems.
