i made a mistake! i thought that one of the blocks did have a pullout like that!!
i was wrong, however i still think that if we can put stuff before pullouts we should be able to put them after as well.
this mainly origonated from this (i dont stand by this opinion anymore btw but i do like this block)
making this with the new vardradic system is (i think?) impossible to get propper grammar for
basically it would act just like the "expand" option but put the inputted text onto the end instead of the front
