TeXmac looks very interesting. I will maybe give it a try. But I must say that TeXmac workflow seems a little bit dependent on GUI. That is not a bad thing per se but seams different form TeX.
In case, for Linux I am using their static binary, if I recall correctly the Ubuntu package wanted to change my Guile to 1.8 and this wasn't ok for me. I have learnt today that Fedora has it in the repositories. The Windows installer works and as far as I know the one for Mac OS too.
