Yes, please. In the re-incarnated-but-not-yet-release ViolaWWW, 
there's an <INPUT type="percent"> which maps to a horizontal slider. 
Perhaps we should add min and max constraints for number inputs.

Not sure we have the same thing in mind, but I've got an <OPTIONS> 
tag (gonna change that name before release...) that is mapped to a 
pull-down menu. In the following example, the menu GUI is initially
labeled ``San Francisco'':

	<OPTIONS name="cities">
	<OPTI value="berlin">Berlin</OPTI>
	<OPTI value="cairo">Cairo</OPTI>
	<OPTI value="sf" checked>San Francisco</OPTI>
	</OPTIONS>

Here's the DTD for it:

	<!ATTLIST OPTIONS
		name	CDATA		#IMPLIED
		type	CDATA		#IMPLIED
		size	CDATA		#IMPLIED
		disabled (disabled) 	#IMPLIED
		envvar	CDATA		#IMPLIED>
	<!ATTLIST OPTI
		value	CDATA		#IMPLIED
		checked (checked) 	#IMPLIED
		disabled (disabled) 	#IMPLIED>


Also, just for the fun of it, there's a signature thingy (type="doodle"),
which draws and collects mouse positions when the mouse is dragged on it. 
Has "clear" button for the doddle pad. Perhaps this is useful enough to 
be part of the HTMLplus standard.
