Does what I want it to do, easy to use

This is a very good plugin, is very easy to use, and is exactly what I’d been looking for – thanks! Could a dotted underscore facility be introduced, please, so that readers can see where a tooltip is located? Right now I’m making use of colour on a trigger word, but I think a dotted line for that word would enhance things. (No problem as it is, it’s just a suggestion.)
