Just found how to add backlinks to TiddlyWiki. It is so simple and your notes are updated automatically.
You need to create a new tiddler with:
<$list filter='[is[current]backlinks[]limit[1]]' variable=dummy>
<hr>
Backlinks: <$list filter='[<currentTiddler>backlinks[]butlast[]]'><$link><$view field="title"/></$link>,</$list>
<$list filter='[<currentTiddler>backlinks[]last[]]'><$link><$view field="title"/></$link></$list>
</$list>And tag the tiddler with $:/tags/ViewTemplate.
I had no idea TiddlyWiki could be so powerful.
