! Disable
You can disable the browser storage plugin:
<$checkbox tiddler="$:/config/BrowserStorage/Enabled" field="text" checked="yes" unchecked="no" default="yes"> Use browser local storage</$checkbox>
! Clear
Click this button to clear browser storage and disable its use:
<$button message="tm-clear-browser-storage">Clear browser storage</$button>
! Save Filter
This filter determines which tiddlers will be saved to local storage. By default, it contains `[all[]]` meaning that it will attempt to save all tiddlers. Other useful values include `[prefix[$:/state/]]` to just save state tiddlers, thus preserving selected tabs, and the open/closed status of table of contents entries.
