Tooltips suggestions

["Giuseppe Bilotta" <oblomov@freemail.it>]

Hello,

I'm now wasting my time on tooltips :-), I thing that I dreamt of for a long
time; and wosh! lots of ideas! Since I like complicated things, I thought of the
following possible spoilments ...er, enhancements... for the tooltips:

* tooltips with non-fixed height (this can be achieved by changing an \inframed
into \framed), so that they can hold mathematics too;

* [connected with the above] multi-line tooltips (\\ does nothing in a tooltip);
this should also imply allowing for multi-paragraph text, and
allowing the user to choose a fixed width for the tooltip; note that the
multiline tooltip can be obtained by passing as argument
{\vbox{\hbox{first line}\hbox{second line}}, but if \box\tooltipbox has been
defined that way, passing {\box\tooltipbox} fails (too many }'s); why is this?

* customizable tooltips (custom background, mostly, and allowing them to appear
also above (not below, as they are now) the text, etc);

* "fixable" tooltips: clicking on the active zone or on them would "fix" them,
clicking again would restore them to tooltip status;

* now the hardest one: foottips/toolnotes or whatever: footnotes that also act
as tooltips (the footnote still being available at the bottom of the page, but
the footnote number being an active); a not-at-all good approximation of this is
the following code:

\def\FootNote#1{\setbox0=\hbox{\postponefootnotes\footnote{#1}}
\tooltip[middle]{\box0}{#1}}

Actually all the above suggestions can be achieved handcrafting a few macros
based on the ConTeXt predefined ones, but I thought it would be nice to have
them prepackaged ...
