+Subject: [PATCH] Plugin support: Properly handle plugin settings
+
+What was done in !92 was strictly speaking only suitable for one plugin.
+This could be extended to several plugins by adding a `.gschema.xml`
+file in `plugins/`, intermediate between the one of the application and
+those of the plugins, or by refactoring the Makefiles with inclusions
+and a single call to `@GSETTINGS_RULES@`.
+
+But in any case, due to the relative rigidity of the `.gschema.xml` file
+format and the internal workings of `glib-compile-schemas`, this would
+only be suitable for plugins that are present at compile time, i.e.
+"fake plugins".
+
+Instead, this commit adds the plugin settings at load time, as is
+natural and as the `GSettingsSchema` documentation states. To do this,
+the setting store is extended to contain several roots: the application
+root and the plugin roots.
+
+For the latter, a unified naming convention is preserved, with the
+prefix `org.xfce.mousepad.plugins.`, but they are in fact completely
+independent of each other and independent of the application root.
+
+Fixes #136, related to !92.
