Upgrading plugins to MS4

Plugin Creator is said to reappear in a later 4.x release.
There is no migration documentation yet.

You can see the error messages in the console window if you start MS4 via terminal. It basically shows the same as the console in the Plugin Creator.

Also note this bug that requires you to restart MS4 in order to reload your plugin after you changed the code.

MS4 seems to use a different QML engine although both 3.6 and 4 use Qt 5.15.2 on my system.

I get QML errors for ToolTip.visible: hovered. Adding hoverEnabled: true seem to work. But it does not work anymore for text labels (Text or MouseArea).

Plugins needs to be "Enabled" in Home -> Plugins to be visible in Plugins menu.

Another necessary changes are:
- add title: "plugin title" below version: "1.0"
- replace Qt.quit() with quit()

pluginType: "dock" doesn't work in MS4. "dialog" still works.
