I’ll be honest, I don’t use Libre Office that much, and when I do use it to transfer my notes from my note pad to my computer with Libre Office Writer. Since you are a writer, you likely have more experience with Libre Office than me, so you are more likely to know what features Libre Office has over MS Office. I did find this something that might help you - it is a comparison of features between Libre Office and MS Office, written by the people who make Libre Office. A lot of these are not likely to be “relevant”, but some of them are.
Such as:
- Stable layout when handling graphics and images
- You can define page and frame styles
- Text auto completion of words previously used (I do LOVE this feature)
- More keyboard shortcuts (for example, in the version of MS Office I have on my Windows side doesn’t have a short cut for a bulleted list, but Libre Office Writer does)
- Export to MediaWiki format (relevant if someone is making a wiki to organize their notes)
I have focused on Libre Office Writer, because that is all I have really used, but you can find the full comparison at the link below.
