2021-05-09 - Added the sync, alpha-focus-hightlight and vim browse patches
2021-05-08 - Added blinking cursor, delkey, undercurl,universcroll, desktopentry, netwmicon and osc_10_11_12_2 patches

- [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
