Fantastic, highly customized tiny addon! Puntuado con 5 de 5 estrellas
Oh, forgive me for my hobbling English!
Let me explain.
Currently the selected word/phrase is a searching pattern. It's OK.
I asked to add the input field to be able also to type what I want to search in case, when the page doesn't contain exactly what I want to search.
Regarding https://addons.mozilla.org/en-us/firefox/addon/fastest-search/ - this addon is about 50 times heavier then yours.
I don't ask to add regular expressions etc.
I want only to be able to type what I want to search - now I can only select.
I mean, that when I select a word/phrase it should appear in this input field, but I can change it - remove something or add - in other words - to correct/edit it manually (if it is needed, of course)
