[Typo3] Backend UI Development

[Brian Slezak]

1. Has anyone implemented, or could anyone give good suggestions toward, a multi-step ui to creating a new 'page', or 'pagecontent' element?  Currently when entering the attributes of a element, all the fields are displayed on one page all at once.  This would extend the current 'new content element' wizard, essentially.  Eg:

One has the need to create an element with unique (within the db table unique), non-auto generated value.  It would work best if the UI, as step 1, only asked for the unique value before continuing.  Then, step 2, the rest of the attributes can be entered keeping step 1's unique value read-only.

2. Is it possible within the current typo3 backend to force a field 'read-only' after the element has been saved?  Eg.  After a value is entered into a field and the element 'saved', or committed to the database, a field can no longer be edited.  A sort of, {if record exists, then field is read-only} logic.

Thanks for all responses.
