Add filter for WIP PRs

[na-Itms]

Feature Description

In the list of PRs, it would be very useful to be able to filter/filter out those that are marked as WIP.

If a full filter is too heavy to implement, a simple "Hide WIP" checkbox could be sufficient.

There is no good workaround:

• The text search for WIP will return PRs which have "WIP" in their content, not necessarily their current title
• There is no possibility to sort PRs by title
• One can create a "WIP" label, which can then be used in the Label filter, but that reduces the usability of the WIP title marker

Thanks in advance for considering this proposal.
