I would like to have editor which would support different text styles and sizes (e.g. each line different font/size/style/color/...)...��

Rubric seems to be able to do it, Morphic is most likely also capable of that.

In the mailing list I also saw TxText, however looking at it yesterday it doesn't seem ready (broken fonts)... so which one would you recommend?

Rubric/Morphic/wait for TxText if soon/something else/...?

Thanks,

Peter
