Use of a special "unique tiddler ID" field has been suggested many times, for both TiddlyWiki Classic and TiddlyWiki5. Typically, after much discussion of alternative architectures and backward compatibility, we generally come back to the fact that TiddlyWiki already has a field that holds a unique ID for each tiddler: the *title* field, and that what is really being discussed is a distinction between a tiddler's ID and the title that people see. In TiddlyWiki5, the "caption" field can be used to provide that distinction. For example, in the <<tabs>> or <<toc>> macros, if a tiddler has a caption field, then that text is displayed as the tab title or table toc link text, respectively. Note that this is simply a TW core standard *convention*. There is no requirement for a tiddler to have a caption field and, by default, only some of the core functions use the caption field. For your purposes, you could extend this default usage to display the caption text in place of the title text, by modifying the $:/core/ui/ViewTemplate/title shadow definition, and replace <$view field="title"/> with <$view field="caption"><$view field="title"/></$view> For links, you could just use *pretty link syntax* to show the desired text, while using the title "ID" as the link target: [[this is what the reader sees|TiddlerID]] or, alternatively, you could use a "caption link" macro to assemble a link using the target tiddler's caption text, like this: \define clink(tid) <$link to="""$tid$"""><$view field="""$tid$!!caption"""><$view field= """$tid$!!title"""/></$view></$link> \end which you would invoke like this: <<clink TiddlerID>> There are probably some other places where you might want some customizations, but once you have tweaked things to suit your needs, you can just think to yourself "title = ID.... caption = display text". Of course, if you don't provide a caption on a given tiddler, everything should fall back nicely to using the title text as the display text, just as before.
