There might be some weird issues with some themes and css snippets out there. For example, I’ve already notice that the space inside an unchecked checkbox seems to stand out in the middle instead of at the bottom.
If you notice anything, let me know and I’ll have a look.
Thanks for the plugin but it doesn’t seem to work. This functionality would be very useful (as a core plugin) for writing. Is it possible to update the plugin in order to work properly for the current editor?
