Settings Preview

[Totto16]

When you change things in the settings regarding style, it would be convenient, to have another window pop up, with the preview of the current item, you are modifying the style of. This would help in several occasions and also would make e.g. choosing a code highlighting style easier, since we could propagate the change only to the preview, until you set those options finally, and only than propagate the new style to all code items, which might take some time to re-highlight the code.

I noticed, that this would be a great addition, while working on #278

I'll try to add that in the future ™️ , feel free to leave any suggestions down below
