Default settings for /siltSuggestion

I don't want people to use the url command. I only want them to use the /silt command for text.

I was wondering if there is an option to make default settings so people dont have to type in a color and font size everytime.

It would be great if there would be a default config setting for font size, text color and background color.

So if someone enters /silt "Hello World!" without any additional parameters it would pick for example white text on red background with font size 14 by default.

That is a good idea.  Will check into it when i can.
