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

- vertically center lines in the space available if you have set a larger chscale in config.h
|

|

- [vim-browse](https://st.suckless.org/patches/vim_browse/)
|
||||
- the vim-browse patch offers the possibility to move through the terminal history-buffer,
|
||||
search for strings using VIM-like motions, operations and quantifiers
|
||||
- it overlays the screen with highlighted search results and displays the current operation
|
||||
/ motions / search string in the bottom right corner
|

|
||||
- [visualbell](https://st.suckless.org/patches/visualbell/)

- adds visual indicators for the terminal bell event
