edit: found a solution for link output...now remain just one thing.....
the regex....and we have hashtag extension again....
010101 the regex that u have found not work at all
but i've invented a new kind of link 😆
the first part work as a complete link(with anchor), the second part could be searched through flarum 😄
smell like a Nobel 👓️
