I am currently evaluating DOpus 12. I want to set an individual headline text for every lister (see red text in picture below)
Hi there. You can use this technique to copy the XML button definition below onto one of your toolbars as a new button, which you can click on and then enter in a title for the current lister only:
<?xml version="1.0"?>
<button backcol="none" display="both" label_pos="right" textcol="none">
<label>Set Lister Title</label>
<icon1>#listerproperties</icon1>
<function type="normal">
<instruction>set listertitle={Rs|Enter the title for this lister...}</instruction>
</function>
</button>
Slight modification to Steje's button from above (see his post for how to use it), so that it still works if what you type has a space, and so the title still includes the current path:
<?xml version="1.0"?>
<button backcol="none" display="both" label_pos="right" textcol="none">
<label>Set Lister Title</label>
<icon1>#listerproperties</icon1>
<function type="normal">
<instruction>set listertitle="{Rs|Enter the title for this lister...} - %p"</instruction>
</function>
</button>
(This will still go wrong if you type a " character in the title, so don't do that. 
)
Oh yeah... quotes
Thanks man
Just forget to say thanks for your help. The new button is a great help to me. Thank you
