If you open the control panel and then use the tools sidebar to switch
themes to and from Starlight, you'll see this tab dynamically appear
and disappear
They look pretty hideous, IMO; the starlight theme is turning into a
bit of a dumping ground of demos of techniques that would be useful in
more skilled hands (embedded fonts, embedded background bitmaps, etc)
No UI for switching themes yet, try these two commands in the console:
`$tw.wiki.addTiddler({title:"$:/theme",
text:"$:/themes/tiddlywiki/starlight"})`
and
`$tw.wiki.addTiddler({title:"$:/theme",
text:"$:/themes/tiddlywiki/snowwhite"})`
