I'm experimenting with the use of styles to see what difference it makes. As I've discussed in my other thread, the thing that complicates that, in this context, is the fact that the sheer volume of different styles that would be required is simply unmanageable. However, I can mitigate that if I use Ctrl+M or Ctrl+shift+M to set the indents, which considerably reduces the amount of permutations, but of course that only works if Ctrl+M and Ctrl+shift+M increase and reduce the indentation by precisely the right amount every time. As far as I can tell from experimentation thus far, removing any individual tab stops ( should you have to do that ...? ) and setting the default tab stop does not necessarily cure the problem - although weirdly, the adding of 0.1mm to the indent amount only happens some of the time.
