Currently there’s only and between multiple columns but I guess that this is an interesting idea.
I would definitely mark this topic as a feature request.
The use case for this would be to create a global search/filter that uses the api. It would be implemented by checking if a value existed in column A OR column B OR column C, etc…
As of right now I’ve been able to create a global search/filter by hiding rows, but this doesn’t work well in conjunction with column filters.
currently we are gathering some ideas but as the major tasks for this quarter are formula support and nested rows functionality we didn’t talked about the new filtering options yet.
