Not sure if this already exist?
I want specific tags, like #Meeting, #Construction to have Header3 but other tags like #Mikael, #John Doe to be just “default”.
So, if using #Meeting anywhere in whole Dynalist, it get H3 by auto.
Impossible with CSS because there’s no selector for text matching. Probably for performance reasons. You would have to do this with javascript and tampermonkey.
