When copying and pasting, preserve paragraph breaks and other formatting

Users have said:

When copy/pasting into the program, all paragraph breaks disappear. It even does so when switching back and forth between documents. Can we get rid of that bug, please? Many thanks.

I don’t know if this is a sudo write thing or not, but every time I copy or past anything sudo write will not stay formatted, so I’m wasting time just hitting the space button to format it all out again. Even though it was formatted before.
Maybe create a button at the top next to the B I U part and chose a format. So High light the whole page, click that format button and chose the format we want. then it would do the whole document?
