tiddlywikis and plan to publish some more of my work. I am developing tools
to do the kind of operation you describe - one is to remove a set of tags:
<$mangletagsextra removeAll=<<stations>> addAll={{!!title}} >
<div class="station">
<$ondrop targeTtag="{{!!title}}" onAddMessage="tw-mangle-tags" >
{{!!title}}
<hr>
<$taglist targeTtag={{!!title}} onAddMessage="tw-mangle-tags" class="btn
btn-primary">{{!!title||$:/kanban/cardTemplate}}</$taglist>
</$ondrop>
</div></$mangletagsextra>
this example uses the parameter 'onAddMessage'to generate a widget message
when a item is added to the list,
which is then caught by mangletagsextra. I am working on some others.
