TODO

• delete devices (do that in key verification popup instead of blacklisting)

• avatar upload/change component

• device list keyboard navigation

• device IP geolocation

• unregister popup/menu when destroyed without being closed

• menu click-through padding to close it easily

• write changelog

• update requirements.txt and flatpak nio version

Refactoring

• Reorder QML object declarations,
  conform to https://doc-snapshots.qt.io/qt5-dev/qml-codingconventions.html

Issues

• Bottom focus line for an HTextArea inside a ScrollView is invisible,
  put the background on ScrollView instead?

• Don't send typing notification when switching to a room where the composer
  has preloaded text

• When calling Backend.update_room_read_marker() for a recent message,
  the marker will only be updated for accounts that have already received
  it (server lag)

• Jumping between accounts (clicking in account bar or alt+(Shift+)N) is
  laggy with hundreds of rooms in between

• On startup, if a room's last event is a membership change,
  it won't be visible in timeline no matter what the user config is

• There are rooms without messages to show as last message subtitle after
  initial sync

• Drag-scrolling in room pane a tiny bit activates the delegates

• Catch server 5xx errors when sending message and retry

• Handle cases where a known account's access token is invalid

• If an account is gone from the user's config, discard UI state last page

• After forgetting a room, it comes back because of the "you left" event

• code, mentions and links in quote ("> http://example.com") aren't properly
  colored in room delegate "last message" subtitle

• Timer and Animation are bound to framerate

• Can't use QQmlApplicationEngine, problem with QApplication?
  See https://bugreports.qt.io/browse/QTBUG-50992

• HTML

  ---

  not rendered

• Pausing uploads doesn't work well, servers ends up dropping the connection
  (no real solution possible?)

Interface

  coroutines. Set disabledWhileLoading to false for all "OK" buttons where
  it makes sense.

Distribution and dependencies

• Use Qt 5.14 for AppImage

• Add AppImage & Flatpak metadata file

• Publish on Flathub and AppImageHub

• Update to Mistune v2.0 when released

Notable changes for future Qt version upgrade

Qt 5.13

• Added SplitView
• Added cache property to icon

Qt 5.14

• Applications can now opt-in to use non-integer scale factors.
  Use QGuiApplication::highDpiScaleFactorRoundingPolicy.

• Added qmlRegisterSingletonInstance function.
  This allows to expose a QObject as a singleton to QML, without having to
  create a factory function as required by qmlRegisterSingletonType.
  It is meant as a type safe replacement of setContextProperty.

• Added qmlRegisterAnonymousType as a replacement for qmlRegisterType.
  It allows to specify the URI and major version for better tooling support.

• qmllint gained an experimental -U option. If run with it, it warns about
  about accesses to unqualified identifiers

• Text and TextEdit now support Markdown format
  (CommonMark and GitHub dialects) as an alternative to HTML.
  Includes the GitHub checklist extension, such that you can click to toggle
  checkboxes in a TextEdit.

• TextEdit uses an I-beam cursor by default, and a pointing-hand cursor when
  hovering a checkbox or a link

• Added WheelHandler, an Event Handler for the mouse wheel, and optionally
  for emulated mouse wheel events coming from a trackpad.

  • Rewrite HKineticScrollingDisabler with it

• Added BoundaryRule in Qt.labs.animation: a PropertyValueInterceptor that
  restricts the range of values a numeric property can have, applies
  "resistance" when the value is overshooting, and provides the ability to
  animate it back within range. It's particularly useful in combination with
  WheelHandler, to provide similar physics as Flickable has.

• Image and BorderImage now have the same currentFrame and frameCount
  properties that AnimatedImage has; this allows choosing an individual icon
  from an .ICO file that contains multiple icons, for example.
  In the future it's intended to support other multi-page formats such as
  PDF, TIFF and WEBP.

• Binding.restoreMode: This property can be used to describe if and how the
  original value should be restored when the binding is disabled.

Qt 5.15

• Introduced inline components
  (ability to declare multiple QML components in the same file)

• Introduced required properties

• Added a declarative way of registering types to QML

• Added support for the Nullish Coalescing Operator (??)

• Added qmlformat tool which automatically formats any QML file according to
  the QML Coding Conventions.

• Added cursorShape property to pointer handlers. Most pointer handlers
  (e.g. DragHandler) will change the cursor when the active state is true.
  HoverHandler will change it when the mouse is hovering over the Item that
  contains the HoverHandler.

• Added selectTextByMouse property to ComboBox.

• Technology Preview: Support for running Qt Quick (2D) on top of
  Direct3D, Metal and Vulkan
