32KB is reasonable enough for a small editor (worked for Notepad, all
those years!) That said, while I don't know what your internals look
like, any editor with an internal structure more complex than "single
contiguous text buffer" should be pretty straightforward to extend to
arbitrarily large sizes. Banking makes things a little more complex,
but if you're already using something like a linked list of lines or
chunks then you only need to tag the links with a bank #, in addition
to the pointer itself.
