Reapply userstyles.css without restarting

Restarting Joplin is a hassle and it makes customizing the css a painful process.

I'd like to see a plugin that can reapply userstyles.css to the markdown rendering. Perhaps the user could choose between using a hotkey or auto-detecting whenever the file has been modified.

And yes, I know about pressing F5 in the development tools, but that reloads everything. It's only barely less clunky and time-consuming than just restarting the app.

Also, to be honest, I'd like this for userchrome.css too, but that might not be as feasible.

Sadly there's still no way to do this that I'm aware of.
