You probably should not use the "common" view for element positioning. You also should not use it to create "extra" elements.
### Theming more than one elements at once
You can theme multiple elements *of the same type* simultaneously. The `name` attribute actually works as a list (delimited by any characters of ` \t\n,` - that is, whitespace and commas). This is useful if you want to, say, apply the same color to all the metadata labels:
```xml
<theme>
<version>3</version>
<!-- Weird spaces/newline on purpose! -->
<view name="detailed">
<text name="md_lbl_rating, md_lbl_releasedate, md_lbl_developer, md_lbl_publisher,
md_lbl_genre, md_lbl_players, md_lbl_lastplayed, md_lbl_playcount">
<color>48474D</color>
</text>
</view>
</theme>
```
Is equivalent to:
```xml
<theme>
<version>3</version>
<view name="detailed">
<text name="md_lbl_rating">
<color>48474D</color>
</text>
<text name="md_lbl_releasedate">
<color>48474D</color>
</text>
<text name="md_lbl_developer">
<color>48474D</color>
</text>
<text name="md_lbl_publisher">
<color>48474D</color>
</text>
<text name="md_lbl_genre">
<color>48474D</color>
</text>
<text name="md_lbl_players">
<color>48474D</color>
</text>
<text name="md_lbl_lastplayed">
<color>48474D</color>
</text>
<text name="md_lbl_playcount">
<color>48474D</color>
</text>
</view>
</theme>
```
Just remember, *this only works if the elements have the same type!*
