It would be nice, if the entries in the style token menu had an indicator, if they are currently used, so you cannot use the same token for different markings by accident (assuming f.i., that you want to mark certain words, but in different colors).

While you are at it, you could add a box showing the color of the style to the menu entries

Is where a specific reason, why there are only 5 different styles available? Is this configurable? For certain tasks/workflows it would be useful to have more styles.
