Hey Matt,

Just to voice my opinion, I think it should be part of the core. This could 
be a great, easy, built-in way to encourage a "Random" option for the story 
river, sidebar, etc. just like wikipedia's 

https://en.wikipedia.org/wiki/Special:Random

Ciao Matt,

It think it is a neat tool with good potential usage. I think it should be 
a plugin. Not in the core. Mainly because most users are unlikely to need 
it.

My two cents

Yes, this would be an excellent use for it.  In the settings -> Default 
Tiddlers box, you can put something like `[shuffle[]first[N]]` and you'll 
get N random tiddlers from the list of all tiddlers.  To be more specific, 
just pass in the input list you want to select from, e.g. 
`[tag[TAG]shuffle[]first[N]]`

[TonyM]

Matt,

I think such a filter operator would naturally be in the core given similar 
support in most languages, and tiddlywiki uses filters to operate its 
fundamental logic.

However this can be dependant on the level of "bloat" to the core. If it 
requires a lot of bytes to implement it should be left out and placed in a 
plugin, perhaps in the tiddlywiki plugin library but documented on 
tiddlywiki.com. It is traditional to present a plugin first, unless you can 
persuade the "developers" over in GitHub or here to include it in the core.

I expect a lot of people would not use this feature, but I can see why it 
would be valuable to some. Text based games, Flash card study notes, 
randomised questions, random stories, daily message, random post etc... 

Regards
Tony

[Mohammad Rahmani]

Matt,
 Good job, thank you!
One question: in TW-Scripts, I like whenever I visit the page a random 
tiddler be shown. Can shuffle operator do that?
I was trying to use Tobias Beer 
macro: https://tobibeer.github.io/tb5/#Tagline%20Macro
