Is there an incremental counter add-on available?

[Stefan Richter]

I want to use trello to keep track of feature requests. Each feature request has its own card and I'd like to add a counter that we can increase by one for every time a customer requests the feature. 

Ideally I'd like the counter to be visible on a closed card.

I searched but couldn't find anything like that. 

Does an add-on like that exist or what are potential workarounds?

Thanks.

Hey @Stefan Richter I do this with a custom field, simple and works quite well :)

Thank you, that would be my fall back option but I could swear I had seen a power-up for it once. Maybe I am mistaken.

Hi.

You can use Smartfields to do calculations in Trello
