Whenever i want to swap fonts or to try a different one is very painful. there are several issues/bad ux with it.

First, if i just scroll down i dont see which font i am currently using. current font should stick and always be visible as a reference

Second, if i type a search for a font, only the first result shows. if i dont type the exact font name (which not always are easy to remember). if i want to choose, say the second option, i don't have a way to do it by search. i'd have to scroll down, not even from the search result position but from the current font which may be too far away. most of the time i end up scrolling like crazy, making it a painful experience. so search is almost useless really

Third, there's no preview of the fonts.
