I'm still unsure whether to add a behavior/effects folder, even if it's hidden by default and only shown in an advanced mode. It's a lot of extra work and I can't really see why it's particularly useful, though I'm open to persuasion.
The logic behind adding something to the bar is that you can do something with it. With the new global variable addition you can add variables or delete old ones; with event sheets you can add/reorder, with resources you can add/remove etc.
