.echo -q $input(Highlight successfully added!,io,Success!)
Could be =>
Noop $input(Highlight successfully added!,io,Success!)
AS for displaying the HLs themselves, would be cool to replace the Actual highlight in the text.
Eg, outputting: Hi Wetty Instead of like, Hi Wetty Might look more professional. Although you may have done that, i don't think you have since i didn't actually test it :o. (Ik you have colours, not bolds, for yours.)
