UDC: Better Separators and Invisibility.

[admin]

UDC is an advanced feature and I think hiding them initially is less intimidating to newbies.

Ok...I'll agree...IF it's clearly documented somewhere so that they'll discover and know about it.

Yes.

Documentation on UDC is clearly lacking currently.
The help file has a little, but quite chaotic and incomplete.
The tour has a small chapter with a few examples: http://www.xyplorer.com/tour/index.php?page=udc
There's no video yet.
The xywiki has the most, but naturally it's overwhelming for newbies I think.

Once there are snippets, it will become much easier to get newbies into digging the power if UDCs.
