Mohammad,
I believe it just came out, so I doubt many have.
On the git hub item I asked if multiple can be strung together, something I
will test soon.
I just tried this to display the caption and if none the tiddler name
<<currentTiddler>>
<$set name=display-title filter="[all[current]get[caption]] ~[{!!title}]">
<<display-title>>
<$link to=<<currentTiddler>> tooltip="Open tiddler"><<display-title>
></$link>
</$set>
However the link opens the non existent tiddler with the caption name
rather than <<currentTiddler>>
Not sure why that would be
Regards
Tony
