virtmon is a script for splitting a physical monitor into virtual ones.
One use case is to make screen sharing better (for the viewer) by splitting a large (ultrawide) monitor into smaller ones that can be shared individually.
Download the script, make it executable and add it to your $PATH.
wget https://raw.githubusercontent.com/nixxxon/virtmon/master/virtmon -q \
&& chmod +x virtmon \
&& sudo mv virtmon /usr/local/bin/virtmon
Run virtmon to split the primary monitor into two equal sized virtual monitors.
