So &xwp; now also goes for features like "sliding focus", "hot corners", and "object hotkeys". These are described in detail on the following pages.

The ultimate goal for this &xwp; component is to replace all those PM hook utilities one day. In my view, several problems exist with those utilities:

1. Most importantly, most of these have not been actively maintained for years. This especially applies to FeelX and NPS WPS, both of which I have been using for years. However, both of them have a few limitations which will never be overcome because they probably won't ever be updated again.

2. Both utilities are not well integrated into the WPS. That is, their settings cannot be changed using the standard WPS notebooks. &xwp; allows you to configure its PM hook using the "Mouse" and "Keyboard" objects in the "System Setup" folder. And NPS WPS always terminates itself when the WPS is restarted, which is pretty annoying.

3. None of the well-known PM hook utilities are OpenSource, except ProgramCommander/2 (which is even public domain). &xwp; is OpenSource, so bugs can be reported and/or fixed by users.

4. Finally, I just hate to install three different PM hooks when I only need a single feature from each of these. Each installed PM hook slows down the system, because every single message which is produced by &os2; and posted or sent to a window must go thru all of these hooks, each of which does a lot of calculations for that message. And we're talking about possibly hundreds of messages per second here. So instead of having three hooks installed which are only partly used, &xwp; attempts to put the most frequently-used features all together in one hook.

For this reason, the &xwp; hook is disabled per default. It must be enabled first in the "&xwp; Setup" object.
