One way LibreOffice could outshine every other suite is by allowing for the handling of custom pronouns.
It’s frustrating for users that try to use any pronouns outside of the generic pre-programmed ones.
For instance:
When trying to use the pronouns Xe/Xir, every correction is either “he x” or “She y”, or it tries to treat it like a place.
A user should be able add it to their dictionary as a pronoun, and click a few boxes to show how it conjugates.
Without this capability, LibreOffice thinks the grammar of “xe said” and “thought xir” are two different things it needs to correct the user on, and if told to ignore one because it’s correct, it cannot make the leap to ignoring the other two!
There are many other pronoun options beside xe/xir, and there are many in other languages as well that could benefit from this additional configuration option.
*edit - I use Linux, primarily, and then Android, i(pad)OS, and Windows; but obviously this should be agnostic to OS. I try to keep to the latest distribution-supported release, so roughly LO 7.1
