For simplicity I wouldn't like a complex structure and I'd like to use a unique term. $all would be nicer, but that would prevent you from using $ in your tags, which doesn't seem likely...

__$ is a more rare prefix 😄

I see haha

Well, it's making more sense but still quite ugly, hehe

😄

Hmm, that's quite an uncomfortable syntax. How does this work with wanting to apply an "AND" logic only to tags, in the task_filter?

Oh, sorry, I messed up, I meant:
task_filter={"tags": ["__$all", "pipe: pipe", "training"]}

Hi SmarmySeaurchin8 ,
This is currently not supported. We'll probably add this in the next release using the following notation:
task_filter={"__$all", "pipe: pipe", "training"}
which will not support complex conditions (i.e. no compound and and or conditions) but will allow you to apply the operator to the entire list...
Does that sound reasonable?

you could do something like 'tags':{'AND':['pipe','training']}
And the user could decide if he wants AND or OR logic
