@switchplayer This might not be what you want, but I'll give a quick explanation of how you could create something like this yourself.
First you want a tiddler to keep your tabs, and then a way to transclude it on every other tiddler.
Create a tiddler called something like
$:/switchplayer/references/tabs, and add the text
<<tabs "[tag[references]]">>. This uses the
tabs Macro to give you a new tab for any other tiddler that is tagged "references". Of course you could choose any tag you want.
Now you want this to appear at the bottom of every tiddler in your wiki, so to do this you add the system tag $:/tags/ViewTemplate.
As of yet you don't have any tabs. You need to create a new tiddler for each tab that you want to see, and within the text of the tiddler create a list of whatever content that you want. Make sure to also give it the tag "references".
So for a simple list of backlinks I might create a tiddler called "Backlinks" and add the following to the text:
<$list filter="[<currentTiddler>backlinks[]]">
<$link><<currentTiddler>></$link>
<br>
</$list>
If I wanted to also transclude the content of each tiddler I might create a tiddler called "Transcluded backlinks" and add the following:
<$list filter="[<currentTiddler>backlinks[]]">
<$link><<currentTiddler>></$link>
<br>
<$transclude tiddler=<<currentTiddler>> mode=block/>
<br>
</$list>
You can now just keep adding new tiddlers with whatever content that you want to display as part of a tab. Hopefully that is helpful.
