This was introduced to make it possible in the new stacked story view
to click on a tiddler to bring it to the front. By allowing a tiddler
in view mode to be focussed, it also prepared for view mode keyboard
shortcuts. (Eg, a key to edit the current tiddler).
However, there are several minor issues with the unexpected behaviour
of clicking on a tiddler navigating to it, so we’ll leave this out of
5.1.8
With this enhancement, clicking on a tiddler in the story view will
navigate to that tiddler. This is needed for eg the stacked storyview,
where we want to be able to click on tiddlers to bring them to the
front of the stack.
There are some problems though - as things stand, clicking on a tiddler
in classic storyview will scroll to the top of that tiddler.

By making sure that all the popup state tiddlers have the prefix
$:/state/popup/ we can be more selective and just exclude popup state
tiddlers when we save. The end result is that once again other kinds of
state are persisted as expected (eg tabs, and sidebar visibility).
By rearranging the `[all[]]` operator we are able to ensure that shadow
tiddlers get processed before ordinary tiddlers. This makes it easier
to create custom stylesheets that override the core.
We get a significant speed improvement of >10% by rearranging filter
operators to bring to the front the operators likely to reduce the size
working list.
Now the ViewTemplate just renders the current tiddler through each
template tagged `$:/tags/ViewTemplate`. This allows plugins (and users)
to add/remove elements from the ViewTemplate easily, without
overwriting the ViewTemplate itself.
(For @giffmex)
Templates are the low-level bits and pieces that allow TW5 to generate
HTML and CSS renderings of tiddlers. The UI folder contains the
user-visible UI of TW5
