Serif, thanks a lot for your work.
2 things I dindn't find how to do, and I'd like to :
- Overlay preview (yes it' can't be exactly the truth, but when I put a yellow bloc on a red bloc, if the yellow one is on "overlay" mode, I have orange when I print, not yellow.
- Set and adjust "défonce" for text and objects. Sorry, I don't know the word in english, but have a look here, you will understand : https://fr.wikipedia.org/wiki/Défonce (if someone could tell...). This is the possibility to get overlay on the edge only, just to be sure to get no lack and not to get overlay inside.
