I am using Open Office and I must admit that for a regular user is as good as Microsoft Office. I want to wish you good luck in making the software better and better every day.
At this point I want to bring to your attention this plugin https://www.arielch.org/aoo/aoo-pdf-import/ . I downloaded it and when I tried to install 360 security said that it has a trojan. Please check it and see if it is really a trojan. Thank you.
