    - [bold-is-not-bright](https://st.suckless.org/patches/bold-is-not-bright/)
       - by default bold text is rendered with a bold font in the bright variant of the current color
       - this patch makes bold text rendered simply as bold, leaving the color unaffected

+   - [clipboard](https://st.suckless.org/patches/clipboard/)

+      - this patch allows you to select and copy the last URL displayed with Mod+l
