I'm going to design a new user interface when interacting with a placemark. The pop-up bubble is not the best option for now.

It can be avoided by only appending 'empty' PolygonNode instances because the region is set by updateRegions(). The only problem would be with virtual nodes: avoid generating the them at each ::paint() call.

ATM what I do is remote the first selected (for merging) node and test if, without it, the node would have a valid polygon. WHAT I SHOULD DO is replace it with the middle point between it and the second selected node and test if the polygon is valid.

The user's experience is very important, so, in order to improve it, the mouse cursor will change according to the actions.

That is because the region is changed by AreaAnnotation::updateRegions().
Check for other redundancies as well.

This would be something like this: select the first node, select the second node and immediately after that the two nodes will start moving one towards the other until they reach the middle between them and get merged.

ATM we are using an Apply button, but it would be more interactive to visually modify the polygons as soon as some values change (colors/lines width, etc) and only have OK | Cancel buttons. BTW, Cancel should undo all changes from the last time the dialog has been opened, so a version of the initial style should be kept.

After the code refactoring, there should be only one action selected at a time.

Highlight nodes when hovering them.

We also need OSM - so a workaround is needed (as the one for loading annotation files maybe?).

When dragging and dropping nods in 'Merging Nodes' state (which is not allowed) the map cannot be moved immediately after that, unless a node is simply clicked (in fact unless a node catches a mouse release event). Starting from this, try to see the design problem.

This means that first they should enter an Editing state other than the current Editing state (which is the default one). This new Editing state would be the state when their dialog would be displayed, just like Google Earth does. This dialog could be popped up by right-clicking and selecting Properties. Or from a menu with all annotate items.

This should be similar to GO.
