[Herve12]

First, A great thanks for your works, i love so much your app, i juste take lkttle time to ask you if it s possible to add certain features, please.
It would be so wonderfull to be able to open multiple windows, in order to see at the same time. 2 or 3 documents. In paralell.
Thanks so much for your attention
I know it s represents so many times and works.
Kind regards
