Duration field should be optional

I'm here, because I wondered what the duration is for and if it is required at all. Nevets, I agree, best answer is nice, but a question can have many answers and even many good among them. So it should be optional.

Expiration actually is optional already. It's disabled by setting to zero. This should be a configuration option (rather than requiring such a field, hiding it and setting it to zero). In config, it is required... (screenshot)

Anyway, this issue is at very low priority for me, too. Just because there are quite obvious workarounds and the simplicity of the module at the current state is appreciated (few space for failure).

Don't forget about #1505098: Undefined Index in question_answer.pages.inc with 7.x-1.x-dev to spare yourself the expiration field. It's in the current dev version only.

In the code, to me it seems there is nothing about expiration done at all, as long as the Vote API module isn't installed.

There is a great need for clarification! Some have the Vote API, some don't, and just by accident it sometime regards the expiration or not. I tend to say (and correct my previous statement) this is a bug! Because you can't use the module reliably without reading the code and setting up fields manually. So, if it's not a bug, it's simply not production quality.
