This may not be the most efficient or elegant way, but here are some
ideas:
Get CoreTweak #444 from
tiddlytools.com. Create your form in a
tiddler called "MyFormTemplate". In some other tiddler, or in the
ViewTemplate, you can then use the macro:
<<newSavedTiddler label:'Add a new tiddler using my form' text:
{{store.getTiddlerText('MyFormTemplate')}} tag:{{'someTag someOtherTag
[['+tiddler.title+']]'}}>>
