* Default to new room list and enforce in config for app and develop

* Update jest tests

* lint

* Update Add -> New Room flow

Keep legacy viewRoomByName until we delete the olds tests.

* Update e2e test to use Add -> Start Chat

* Update screenshots

* Fix viewRoomByName, can't use option as it contains more that just the room name. Using title which should be exact.

* Fix knocking tests

* fix layout.spec.ts and pstn.spec

* timeline snapshots

* Fix spotlight.spec

* TAC spaces and media preview settings

* Fix more screenshots and mark as unread tests

* Fix leftpanel test

* Bugfix for knocking use case. We should check EffectiveMembership when remove rooms from the new room list, so that knocking is handled

* Fix openCreateRoomDialog to new room list specifics to fix create-knock-room.spec.ts

* lint

* Fix Landmark navigation from left panel search to the next landmark

* lint

* Update window-12px-linux.png

* Update apps-drawer-linux.png

* Update sliding sync e2e tests

* Update some screenshots

* Revert change to the space create screenshot

* Use actual screenshot

as focused elements are different when generated locally

* Fix test selectors

* Morfe test screenshot selector / update

* Add test for landmark navigation

* Replace screenshots

* Fix another test that just got added an hour ago

* Not sure why this was changed, doesn't seem necessary

* Disambiguate selector

* Another screenshot that's now changed in width by 1px

* Revert changes to config files

It's being turned on by default so these are unnecessary

* Convert read.unread assertions to new room list

removing support for checking for activity in assertUnread which was
unused.

* Update room list order tests

that feel a bit like they ought to be in room-list rather than read-receipts but whatever

* Fix room titles in read receipts test
