Format text depending on tag or at least allow formatting several nodes at once

Explain the problem as you see it

As it is now, it is really difficult to distinguish between imported text and text I've written myself, because the formatting options are so limited.

Why is this a problem for you?

When writing a book, I regularly import text from articles for future reference and then I need to distinguish between

• What was imported from an article
• What I've written myself.

It's common to every academic.
Unfortunately, Tana does not allow e.g. a tag named "quote" to be automatically formatted as italics or a different color etc. (Or am I missing something?)

Suggest a solution

Being able to define text formatting (color, italics) in the supertag configuration would be a huge help and probably relatively easy to implement.
Alternatively, it would already help if one could select several nodes and apply e.g. text color formatting or even just italics to them, but as it is now (Juli 23), that's not possible, you can only format one node at a time.
