"is it possible to fix these in LibreOffice?"

problems with writer: ctrl+shift makes the format change from left to right to right to left. Dictionary needs to be easier to access. Empty lines will be look like a bigger font size despite being same the size as the rest of the document. Pasting stuff does the following: makes the pasted stuff go to the next page if it’s under the original text. Sometimes changes the font sometimes the bottom part of the pasted text

problem with spread sheet:
it asks me to change the sort range when I alphabetize stuff. for exmaple, if I want to alphabetize column G, it’ll ask me to extend it to everything, even though I don’t. If I want to sort multiple columns, I’ll highlight them myself.
