How to create a view of surveys not answered by the current user

Hmm, good question. I'm not sure if it's currently possible to add a relationship to the vote table in a view to check if a user has voted. Might be better to write a custom view plugin or something that does this logic, as a relation ship on the votes table is probably way too heavy.

It's a shame that this module is so limited, because when I look at my survey view, there are almost no filters.

This is opensource, bro. If you want some cool features, you need to develop or sponsor it.

This is the first time I personally see this requirement as well. It should not be too hard to create an implementation for this. But I personally have no time for this.

Classifying as feature request. Feel free to work on this and provide an issue fork / merge request.
