@Leia Thanks for your feedback, updated it.

• xdotool needs to be appended to the dependencies.
• Line 28 needs to be updated to:

ln -sf "/usr/lib/libxdo.so.4" "${pkgdir}/usr/lib/libxdo.so.3"

@eurpto It's useless.

Cannot run 0.15.0-1 with new dependency libxdo.so:

donutbrowser: error while loading shared libraries: libxdo.so.3: cannot open shared object file: No such file or directory

Current installed latest version is libxdo.so.4 from package xdotool.

Temporal workaround by symlink:

sudo ln -s /usr/lib/libxdo.so.4 /usr/lib/libxdo.so.3

@fredrics Thanks for your feedback, fixed it.
