Hi Peter,

Combined with a depends=, it would allow the a textarea's size and position
to be dependent on the existence of another element.  For example:

        <textarea name="description+sub" depends="subtitle">
            <area>0,80,-5,100%</area>
            <minsize shrink="short" vanish="true">100%,40</minsize>
            <align>left</align>
            <font>mydesc</font>
            <multiline>yes</multiline>
            <scroll direction="vertical" rate="10" returnrate="70"
                    startdelay="17" returndelay="17"/>
            <cutdown>no</cutdown>
            <template>%|RATING| %%|(STARS|) %%DESCRIPTION%</template>
        </textarea>

        <textarea name="description+notsub" depends="!subtitle">
            <area>0,45,-5,100%</area>
            <minsize shrink="short" vanish="true">100%,40</minsize>
            <align>left</align>
            <font>mydesc</font>
            <multiline>yes</multiline>
            <scroll direction="vertical" rate="10" returnrate="70"
                    startdelay="17" returndelay="17"/>
            <cutdown>no</cutdown>
            <template>%|RATING| %%|(STARS|) %%DESCRIPTION%</template>
        </textarea>

Would allow the position of the description area to be dependent on the
existence of the subtitle.

I was trying to make it "generically" useful, but I may end up just hacking
MythUI to have "description" and "description1" to allow me to pull that
example off, without the performance penalty.
