Hi Hans,

this is a feature request regarding fieldstack based animations.

Since i want to use fieldstacks in one of my modules i’m looking for
a simple to use interface to produce animations, for the moment i create
a symbol for each frame and put them together with a fieldstack.

For latex there is a package called animate [1] which provides a environment
to produce animations with buttons for navigation (just a take a look at
the examples in the manual, code is not relevant for us).

I wrote now a short dummy module [1] to demonstrate how this could look
in context, the first file [1] contains a few example, the environment
is inspired by \startoverlay/\stopoverlay but it needs a alternative
method to allow loops (look at the third example in this file).

The second test file shows which navigation buttons i want for such
a module, the are “first frame”, “previous frame”, “play” and “stop”
animation, “next frame” and “last frame”. As a alternative one can
produce a animation with a overlay button only with a symbol on the
first frame to indicate a interactive element.
