Your MiniIDE has default layouts, because you added them to the menu.
Same can be done by an IDE package that registers a dock master.

Overrides don't compile anymore.
If you still don't understand this, please read the fine manual
about virtual methods.

You are free to implement this in your dockmaster.
Maybe I will implement this as an option in anchordocking.

For anchordocking the simplelayout is only important, when the user
uninstalls/deactivates anchordocking. That's why simplelayout should
store screen bounds of docked forms.
If I understand you correct, you want to use simplelayout in parallel
with your dockmaster, right?

AFAIK Screen.Monitors changes when switching to another workspace.

And it seems the monitor bounds are not always correct from the
beginning, for example when the IDE creates its first window and calls
restore layout. This seems to be a general problem on all widgetsets.

ok. Probably not in the next two weeks.
