- reflow
- allows st to be resized without cutting off text when the terminal window is made larger again
- text wraps when the terminal window is made smaller
- [relativeborder](https://st.suckless.org/patches/relativeborder/)
- allows you to specify a border that is relative in size to the width of a cell in the
terminal
