 Once you know what you are doing, all of these things are actually pretty easy to do. There are two steps involved:
 
-! Add or remove shadow tiddlers from the user interface
-
-In the More > Shadows tab you will find a list of all the shadow tiddlers. In this list you will find many tiddlers with the prefix `$:/core/ui/`. These are the core tiddlers that define the user interface. These tiddlers are tagged with SystemTags, and removing or adding these tags will adjust the tiddler and page layouts.
-
-For example, $:/core/ui/SideBar/More is the tiddler for the More tab in the Sidebar, and it is tagged with the SystemTag `$:/tags/SideBar` so that it appears in the Sidebar. Removing the tag from that tiddler will remove the More tab from the Sidebar, and reinserting the Sidebar tag to that tiddler will make it reappear in the Sidebar. 
-
-You can use the same process for any of the core user interface tiddlers with the $:/core/ui/ prefix. For example, removing the SystemTag `$:/tags/ViewTemplate` from the tiddler `$:/core/ui/ViewTemplate/subtitle` will remove the subtitles from all tiddlers.

 ! Adding custom-made tiddlers to the user interface
 
 You can also create any tiddler you want and tag it with the appropriate SystemTag, and it will appear in that place. For example, if you create a tiddler 'Reminder to self', add the text 'This is a reminder' and tag it `$:/tags/EditTemplate`, the words 'This is a reminder' will appear inside every tiddler when you edit it.
