separate WIP from non-WIP merge requests
Description
This is a minor user-interface request. I find that when reviewing merge requests, it can be difficult to visually pick out the ones that are ready to merge from the works-in-progress, when all of them are listed together. I would find it helpful to have an easy option to either omit WIP-tagged MR's, or to sort them to the bottom of the page.
Proposal
To the tabs across the top (Open, Merged, Closed, All), add another tab labeled "Ready". This would display a subset of "Open" MR's, but with works in progress omitted.
