@psychobunny I'm making a more advanced plugin with this idea, I hope you don't mind!
I'm not very good at English, so if a post i made isn't good, please forgive me, and tell me what is wrong so I can change it :) thank you!
maybe the language file
here it is
the line is
"composer.title_placeholder": "Enter your topic title here...", if you change it and restart nodebb it would be working
@baris I got it,thanks
Do you wanna share it?
