For connectors.

These are all of a etoys networking experiment.
I do not think they are of much use to students unless they are
enhanced quite a bit

This is a basic calendar.
It has a few tiles associated with it

Dr Geo is a whole book of features. http://www.drgeo.eu/

> Flap

Flaps are a very useful widget that you can use to hold and hide
objects of all sorts. You can have local flaps that hold objects in
just the current project ( viewers are local flaps). You can have
global flaps that you can access in all projects (the help flap and
the 'gold box ' are global flaps). Flaps are basically a PasteUpMorph
that can slide in and out from the edge of another PasteUpMorph. You
can use the same settings for flap panes as for PasteUpMorphs.
Flap tabs can be edited for name and color, edge bevel etc.

I do not know much about these objects.

This is part of connectors. Could probably be hidden. Quite buggy.

Some experiment have been done. Nothing I know of that is 'student ready'.
