Good question. I use the German text table for both languages cause I'am used to the German braille
symbols and cause of the English characters are a subset of the German ones. But of course this
isn't valid for other languages. And I don't use the contraction table. At this point I'am
absolutely not qualified to answer. I only know, that different languages have different contraction
tables and I could imagine, that someone uses contractions in his native language but not in other
ones. So in my opinion it would be the easiest way to officially do, what I'am already practicing:
let the user define multiple brltty.conf files for different settings. Advantage is, that the user
can define what he wants and so is very free in creating profiles. This includes all speech output
settings, text and contraction options and more like choosing the key table. You only have to define
a key combination to switch between them and after that reread the config file.

Depends how others use the marks. Maybe the best solution for that is: don't touch the currently
implemented SETMARK and GOTOMARK functions but create the following new ones:
1. Make all marks permanent. This function saves all currently set marks to disk.
2. Reset all marks. Here all marks are set to line one again.
If you don't want to save the marks nothing changes for you. But I can mark my wished lines one by
one with the Capslock+ShiftLeft+!One-!Four shortcut and when I'am satisfied I make them permanent.

By the way: Brltty still runs without braille and speech issues, very good.

Cheers
