[NTG-context] Visually balanced columns

Hi list, I'd like to know if its is possible to get visually balanced mixedcolumns in lmtx. For example, if I have \blank's between paragraphs, I would like them to be stretched or expanded by a such way that the bottommost lines have the same vertical position -- no matter, how many lines there are in each column and how exactly they are aligned. If I understand correctly, that's how the multicols environment in LaTeX works, and that's how old-multicolumns worked -- but this module seems to be no longer supported in lmtx. I tried to disable gridfitting for startcolumns, but it produces a completely distorted output. -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History
