Collapsible columns in the Board view

We have a maybe too big workflow which includes things like Deployed to Development, Deployed to Staging and Deployed to Production ... in the List view it works fine. But in the Board view this have the effect of spreading the columns a lot, generating a lot of horizontal scroll. We love the Board view, that's something that Wrike need a lot but we also love our expressive workflow. A lot of boards based solutions use collapsible columns to handle this issue, any other ideas?

Hi Aníbal, thanks for posting another interesting idea! Do you see this being similar to filtering by different statuses, so you could choose to see certain statuses individually or in groups, like in the List View?
