[Q] adding tiles to Plugin?

[Scott Wallace]

Hi, Anindita,

The Plug-in image and the mainstream image have deviated considerably 
by now so there are a number of things that behave quite differently 
between them.

In this case, after taking all the (correct) steps that you describe, 
you need to evaluate "Vocabulary initialize", and then things should 
straighten out, and you should see your newly-added items in viewers. 
In the mainstream image, whenever an #additionsToViewerCategories 
method is recompiled that reinitialization is invoked automatically, 
but not in the plugin.

Incidentally, all "non-universal" categories occur "below the line" 
-- this is not a bug but rather the way it's designed to be.  The 
items and the order of the universal "above-the-line" category list 
are hard-coded; if you want to modify that, edit method 
Morph.categoriesForViewer -- insert any new categories that you want 
to appear "above-the-line" *before* #miscellaneous in the list 
defined there.

Cheers,

  -- Scott
