TiddlyWiki defers processing changes to draft tiddlers and tiddlers with the prefix $:/temp/volatile/ until a timeout has elapsed (this is called throttling). The mechanism can be extended to other tiddlers by adding a throttle.refresh field. See RefreshThrottling for details.

The default value of 400ms gives a good balance of responsiveness in most cases but isn't always optimal on lower powered mobile devices.

The timeout can now be changed by changing this value (in milliseconds):

$:/config/Drafts/TypingTimeout
