Bug 158275

Would it be possible to add a "split Window" feature (in the "View" menu) in Libreoffice writer?

I simply do not understand why this so useful and basic feature is not implemented while it is in Libreoffice Calc?

Some may say that there is already a built-in equivalent with "Window - New Window" which I completely disagree. First, this option opens a new instance of the file and takes much more screen space which can be a problem on small laptops for instance. Second, because it is another LO Writer's instance, the whole menu on the top and the icons are also present which makes less available screen. Third, the "split screen" option is quicker because there is no need to move any window, which improves the workflow. 

If already implemented in one of your software (LO Calc), why not adding it to LO Writer? Is it a patent problem with MS Office which offers that option?
