Newly installed versions of the engine will now attempt to copy the project-agnostic config settings from a previous engine installation. This happens by way of a versioned manifest that copies old versions when the manifest does not exist, or is a different version. This code path is benign for non-installed versions of the engine (or FPaths::ShouldSaveToUserDir() is false).
EditorGameAgnosticSettings and EditorUserSettings ini paths have been renamed to EditorSettings and EditorPerProjectUserSettings respectively to better convey their purpose. In general, most settings should be saved in EditorSettings (project-agnostic) so that they apply regardless of which project is open. We have some way to go migrating existing settings for this to be the case, however.
Some previously per-project configuration files are now project-agnostic (such as Editor.ini, EditorKeyBindings.ini, and EditorLayout.ini)
GEditor->Access...Settings and GEditor->Get...Settings have been removed in favor of direct access of the CDO through GetMutableDefault<> and GetDefault<> respectively. Global config ini filenames that are not set up are now neither loaded nor saved on build machines, to handle the problem of indeterminate state more generically.
This addresses UETOOL-270 (Most editor preferences should be project-agnostic)

When a selected actor is reinstanced, a details view (displaying details of the actor) needs to be refreshed.
An alternative solution: don't check SDetailsView::ShouldSetNewObjects (refresh always )
OR store an object's hash in SDetailsView (and compare it in the ShouldSetNewObjects)

Actor pilots are now initiated from the actor's context menu, rather than an unrelated menu on the viewport. Similarly, pilots can be stopped via the context menu for the actor, or from the viewport toolbar that is visible when a pilot is active.
This addresses UE-1091 - Allow actors to be piloted with the camera in UE4.

Editor selection outline now uniquely identifies selected components. When a component is selected directly the rest of the actor gets a subdued selection color and the selected compoent(s) get the normal selection color. When the actor is selected directly all components get the normal selection color.

Editor - Fixing a bug where decorators dragged over the viewport that don't create something in the world (materials) are not properly restored when dragged out of the viewport.
[CL 2433332 by Matthew Griffin in Main branch]
Improved the validation when drag-and-dropping a class into the level viewport
UE-7184 - Show game c++ classes and engine c++ classes in the content browser
It now prevents the placement of non-placeable classes that have come from an asset or class drag (Content Browser or Class Viewer).

UETOOL-213 - Minimize Slate FString -> FText conversion (remove SLATE_TEXT_ATTRIBUTE)
This fixes any editor/engine specific code that was passing text to Slate as FString rather than FText.

- SEditorViewportClient now has an additional optional parameter in its constructor for the SEditorViewport that the client is attached to
- SBasePoseViewport, SDestructibleMeshEditorViewport, and SPhATPreviewViewport were all updated to inherit from SEditorViewport (previously just inherited from SCompoundWidget)

Introduces the concept of "Active Ticking" to allow Slate to go to sleep when there is no need to update the UI.
While asleep, Slate will skip the Tick & Paint pass for that frame entirely.
- There are TWO ways to "wake" Slate and cause a Tick/Paint pass:
1. Provide some sort of input (mouse movement, clicks, and key presses). Slate will always tick when the user is active.
- Therefore, if the logic in a given widget's Tick is only relevant in response to user action, there is no need to register an active tick.
2. Register an Active Tick. Currently this is an all-or-nothing situation, so if a single active tick needs to execute, all of Slate will be ticked.
- The purpose of an Active Tick is to allow a widget to "drive" Slate and guarantee a Tick/Paint pass in the absence of any user action.
- Examples include animation, async operations that update periodically, progress updates, loading bars, etc.
- An empty active tick is registered for viewports when they are real-time, so game project widgets are unaffected by this change and should continue to work as before.
- An Active Tick is registered by creating an FWidgetActiveTickDelegate and passing it to SWidget::RegisterActiveTick()
- There are THREE ways to unregister an active tick:
1. Return EActiveTickReturnType::StopTicking from the active tick function
2. Pass the FActiveTickHandle returned by RegisterActiveTick() to SWidget::UnregisterActiveTick()
3. Destroy the widget responsible for the active tick
- Sleeping is currently disabled, can be enabled with Slate.AllowSlateToSleep cvar
- There is currently a little buffer time during which Slate continues to tick following any input. Long-term, this is planned to be removed.
- The duration of the buffer can be adjusted using Slate.SleepBufferPostInput cvar (defaults to 1.0f)
- The FCurveSequence API has been updated to work with the active tick system
- Playing a curve sequence now requires that you pass the widget being animated by the sequence
- The active tick will automatically be registered on behalf of the widget and unregister when the sequence is complete
- GetLerpLooping() has been removed. Instead, pass true as the second param to Play() to indicate that the animation will loop. This causes the active tick to be registered indefinitely until paused or jumped to the start/end.
