It would be a killer feature to be able to enter
formulas right in the wiki. Also, entering things like
\Alpha, \Gamma and so on is a bit more intuitive than
Α.
Could use that for
http://www.kiesler.at/index.php?module=wiki&page=LogischeSysteme
and a lot of other pages. For example, how would you do a
|[ without LaTeX? It is in fact a square bracket with
two lines.
Or how about a X_i? That would be a X with a subscripted i.
Or a |- or a |= ? That should in fact be all characters
of their own.
