What do you mean exactly? As a blackbox - as a regular, repeatable method?

This might be a good use case for the proposed unload function
(http://zdharma.org/Zsh-100-Commits-Club/Zsh-Plugin-Standard.html#unload-fun).
If you would provide a function powerlevel10k_unload_plugin, then I
would call it in Zplugin when unloading the plugin, allowing the
function to close the background process.
