The very useful addon that displays a call tip colour-swatch when hovering over a legit colour hex value, is unfortunately a little overambitious when it parses text for a hash character followed by a string containing letters A-F, it seems.

For textual contexts in which misinterpretations become frequent this can be quiet annoying. Specifically, whenever the cursor "touches" an occurrence of a #define-directive (in a C-file), a lightblue calltip swatch keep popping up, blocking the text! The bug here, of course, is the fact that the string #DEF... is simply interpreted as a hex value.

I don't know how this functionality of the plug-in can be made to robustly distinguish between "correct" hex strings and C-like directives, for example. Perhaps an option to check for file type, so it doesn't even try parsing files with certain filename extensions like .c, .h., .cpp, .ino etc?
