Hi, Massimo.
Thank you for sharing your software, it is a nice software, compact and safe and convenient, I tried it, and found a few problems, I want to tell you:
1, if I only changed the format, but did not change the text content, when I switch to other nodes, then switch back, the format of the change will not be saved.
2, if I did not selected any text, accidentally click the "bold, italic, underline" button, then the entire paragraph format will be overwritten, leading to the loss of the original format.
I hope your software is getting better!
