There are two parts to these changes. The key is a new [[Cascade Filter Run Prefix]] that takes a list of filters and runs them in order, returning the result of the first one to return a value. It forms the basis of a new flexible mechanism for choosing between multiple options. The second part is a series of improvements based on this new filter cascade mechanism:
* Story Tiddler Templates
* View Template Body
* View Template Title
* Tiddler Colour
* Tiddler Icons
The cascades can be inspected in $:/ControlPanel under ''Info'' -> ''Advanced'' -> ''Cascades''.
!! <<.link-badge-added "https://github.com/Jermolene/TiddlyWiki5/pull/6148">> New LetWidget
The LetWidget is an improved alternative to the existing VarsWidget. It is recommended to use the new LetWidget instead of the VarsWidget in all circumstances.
The chief advantage is that the LetWidget performs the variable assignments in the same order as they are written, and permits references to earlier assignments. For example, here we swap the values of two variables:
```
<$let temp=<<foo>> foo=<<bar>> bar=<<temp>>>
...
</$let>
```
