TO DO	QSqueezedTextLabel, or squeezing in QLabel	?	<{{{3}}}>
TO DO	QFileSystemWatcher: support for watching non-existing files	David Faure	<{{{3}}}>
TO DO	QCompleter: many missing features compared to KCompletion. Look at the completion model in http://qt-project.org/wiki/Qt-5-Ui-Helpers as a possible replacement which would also work for QML.	?	<{{{3}}}>
TO DO	QLocalSocket/QLocalServer: support for abstract unix sockets	Thiago?	<{{{3}}}>
TO DO	KProcess/KShell features in Qt?	Ossi	<{{{3}}}>
TO DO	KProcess ForwardOnlyStdErr/ForwardOnlyStdOut features in Qt?	?	<{{{3}}}>
TO DO	QCursor: auto-hide support (see KCursor API), plus styleHint to enable this in QLineEdit/QTextEdit (and let users turn this on/off in KConfig)	?	<{{{3}}}>
TO DO	QCursor: theme support	?	<{{{3}}}>
TO DO	QIcon: support for overlays	?	<{{{3}}}>
TO DO	QPushButton: support for delayed menu	?	<{{{3}}}>
TO DO	QSystemTray: support for the new dbus protocol (see KStatusNotifierItem)	?	<{{{3}}}>
TO DO	QRecursiveFilterProxyModel	Stephen Kelly?	<{{{3}}}>
TO DO	QPoTranslator (support for .po files, and locating them with QStandardPaths, so that libs can load them?)	??	<{{{3}}}>
IN PROGRESS	QLineEdit: support for clear button	Kevin Ottens
DONE	QLineEdit: support for text squeezing	Kevin Ottens (only one user and half-broken feature anyway, cancelled)
TO DO	QLineEdit: support for URL drops (replace existing text, rather than append)	??	<{{{3}}}>
TO DO	QComboBox: support for URL drops (replace existing text, rather than append)	??	<{{{3}}}>
IN PROGRESS	QTextEdit: support for place holder text like place holder text in QLineEdit	Benjamin Port

TO DO	Merge KStandardShortcut and QKeySequence::StandardKey	??	<{{{3}}}>
TO DO	Rewrite QKeySequence::StandardKey to get the default keys from QPA, not just an enum. In KDE we can make the shortcuts configurable this way.	??	<{{{3}}}>
DONE	QTabWidget: give the possibility to hide the tabbar (used in many places if count is 0). Preferably called setTabBarHidden(bool) / isTabBarHidden() (then deprecate ktabwidget). RESULT: Since the exact same functionality can be achieved with tabBar()->hide(bool) and tabBar()->isHidden(), no methods have been added to QTabWidget and both KTabWidget methods have been deprecated.	David Gil
IN PROGRESS	QTabBar: port signals from KTabBar	Ivan Komissarov (https://codereview.qt-project.org/#change,29650)
DONE	Add support for default vs active shortcuts to QAction (implemented in KActionCollection instead)	Kevin Ottens

IN PROGRESS	Add the color picker button to QColorDialog (KColorDialog has it)	David Gil
TO DO	Make sure we have a QAction independent of QtWidgets in QtGui	??	<{{{3}}}>
TO DO	QToolBar should take its default settings from the global settings when running in a Plasma Workspace session (see loadKDESettings from KToolBar)	??	<{{{3}}}>
TO DO	QMainWindow should follow the KDE HIG when changing the window title in a Plasma Workspace session (see KMainWindow::setCaption)	??	<{{{3}}}>
TO DO	Support for timer-based auto-selection in QAbstractItemView (triggered by styleHint, like QStyle::SH_ItemView_ActivateItemOnSingleClick triggers single-click mode)	??	<{{{3}}}>
TO DO	QInputDialog should have an equivalent of KInputDialog::getMultiLineText	??	<{{{3}}}>
TO DO	QInputDialog should have an equivalent of KInputDialog::getDouble with configurable step	??	<{{{3}}}>
TO DO	QInputDialog should have an equivalent of KInputDialog::getItemList (multi-choice, not single choice like getItem)	??	<{{{3}}}>

DONE	Make sure QDesktopServices can list the protocols it supports	Kevin Ottens (Turns out it's not even possible to know before hand with xdg-open for a start... It's not really essential anyway: cancelled)
IN PROGRESS	Make sure QNetworkAccessManager can list the protocols it supports	Kevin Ottens (https://codereview.qt-project.org/51088)
TO DO	Add icons to QTextBrowser context menu	??	<{{{3}}}>
TO DO	Add support for "whatsthis:/text" urls to QTextBrowser	??	<{{{3}}}>
TO DO	Make sure QTextBrowser automatically follows KDE settings for the wheel button behavior (scroll vs zoom) via backend	??	<{{{3}}}>
TO DO	Allow to register a default syntax highlighter type for QTextEdit, the KDE backend would register the spell checking one coming from sonnet as default	??	<{{{3}}}>
TO DO	KSsl/QSsl merge	Richard Moore	<{{{3}}}>
DONE	Create QPA theme plugin for setting KDE palette, font, widget style, etc. (in KDE), will require extensions on the Qt side, look at KGlobalSettings, some of it is there	Kevin Ottens
DONE	Extend QPA theme plugin to use KIconLoader within QIcon::fromTheme()	Kevin Ottens
TO DO	Make sure the QPA plugin can properly react to setting changes	?	<{{{3}}}>
TO DO	Restore the _NET_STARTUP_INFO from Qt4 that got lost (work for the xcb backend)	?	<{{{3}}}>
TO DO	Restore QSessionManager from Qt4 that got broken	?	<{{{3}}}>
IN PROGRESS	Extend the QStyle API so that the styleHint() can control the default value for animated widgets (should animate or not by default?)	Àlex Fiestas
TO DO	Extend the QStyle API so that the styleHint() can control the default value QSplitter::opaqueResize	?	<{{{3}}}>
