[Dev] Unusual collections and items

[Heikki Toivonen]

We have some unusual collections, like Scripts and Certificate Store,
that behave somewhat differently than your typical collection of events,
tasks and so forth.

This leads to interesting situations I am not sure how to solve, so some
design decisions are called for. Here are some examples.

You have Certificate Store selected in the sidebar. Arguably you should
not be able to create/move non-certificates into this collection. I
don't  think we have any support for that (I am pretty sure you will get
exceptions raised if you try). And you need different type of feedback
to the user so that they won't even try or if they manage to try give
some useful feedback that it is not supported (create event from menu,
copy/paste, drag & drop, double click, ...).

You have Scripts selected in the sidebar. You click on Calendar toolbar
button. Currently what happens is that the toolbar buttons seems to be
selected but you get an empty summary table view. While at first glance
it would seem it would be ok to disable the toolbar buttons that don't
make sense, this will lead to a situation where the user does not
understand why they can't switch to the calendar, for example.

You can actually stamp a certificate to an event, for example. For some
reason this does not show up on the calendar - seems like a bug. At
first glance you might say it is stupid to stamp certificate and
stamping should be disabled for certs, but if you think of the case
where you are buying certificates (which expire yearly) you'd like to
have a calendar reminder to renew the certificate before it expires. And
come to think of scripts, why not make it possible to stamp scripts too
- a script event could run at the specified time etc.
