+// This class is now mostly finished, except one thing, it is a global
+// object. This will not do. The user (and layout files) are free to
+// create floats and modify them to fit into a certain document. So it is
+// pretty clear that each layout needs its own list, as do documents.
+// However this is also not enough since we really want the user to be
+// able to create "presistent" floats, in the sense that a user created
+// float can be used across sessions and across documents. So we need a
+// global¹ floatlist as well. The interaction between these are not quite
+// clear, but it seems natural that the definition found in the document
+// takes precedence.
+// We also have the issue about what get stored _in_ the lyx file.
+//
+// ¹ not absolutely global but somewhere where documents,layouts and
+// the bufferview can have access to it.
