Unfortunately, it is not not working with MS Excel files. I was enthusiastic and a lot of gestures are faster ni Libre Office, but I have now a large, complex file, and it takes a minute for each action to do in that file, when opened in Libre Office.
It could function in completely Libre Office environment, where all users are using it. But goverments and nations must introduce it instead of MS Office, and they will not because of lazyinees or profits.
