It has been talked about for some time that the views listing page should have a search field to filter the view listings down. This is not a massive issue right now, as most of us are just using (pretty much) a vanilla D8 installation with (I think) under 10 default views. What about a larger site, with 50 views?
Add a search field on the views listing page, similar to that on the module listing, and block listing pages. It would use pretty much the same JS. I also think this should include the name AND description fields in the filtering.
Patch, reviews (including a review from at least one of the JS folks), testing.
JS could do with a bit more work - Currently if E.g. there are no disabled views after filtering the table header will still be there. We want to iterate over each table (I think) and if there are no rows after filtering, just hide the the table.
User interface changes
New dynamic search field on views listing page.
