    - [vanitygaps](https://github.com/bakkeby/dwm-vanitygaps/blob/master/patches/dwm-vanitygaps-6.2.diff)
       - adds configurable gaps between windows differentiating between outer, inner, horizontal and vertical gaps
 
+   - [warp](https://dwm.suckless.org/patches/warp/)
+      - warps the mouse cursor to the center of the currently focused window or screen when the mouse cursor is (a) on a different screen or (b) on top of a different window

    - [windowrolerule](https://github.com/bakkeby/dwm-vanitygaps/blob/master/patches/dwm-windowrolerule-6.2.diff)
       - sometimes a single application opens different windows depending on the task at hand and this is often reflected in the WM_WINDOW_ROLE(STRING) x property
       - this patch adds the role field to the rule configuration so that one can differentiate between, say, Firefox "browser" vs "Preferences" vs "Manager" or Google-chrome "browser" vs "pop-up".
