Changing article to report/book, math+\text{} problem

[Karsten Heymann]

Hi,

1. are there plans to support changing chapter<->section when changing the 
documentclass from article to report/book or back? It's a bit annoying to change all 
sections&co when changing from article to report. Wouldn't that be nice?

2. (1.3.0:) when I type in the following in math mode:
  \text<SPACE>H<RIGHT>_xy
  then xy is roman too although <RIGHT> should move out of the \text
  inset. I  have to do
  \text<SPACE>H<RIGHT>X_xy
  and delete the "X" afterwards instead. 

Yours,

Karsten
