Hello! Currently using a widget showing the day of the week and day of the month. When the date is 'the Twenty first', the widget shows it as 'Twenty onest'. Is there any way to fix that? Thanks. 
Hello?
Yeah probably the theme author just used $tf(n2w, df(d))$$tf(ord, tf(n2w, df(d)))$
There is no way to fix this at the moment because Kustom only allows to express ordinal suffixes based on numbers so it will write "st" after "1" but not ordinal numbers written as text. You can open a request in the ideas forums if you want to have this implemented.
