how multi-tag columns work
you search for a hashtag open it in a column - pin that column - open settings for that column - input other tags related to the first tag
you'll notice the first tag will only show at top of column
you can also input tags you don't wanna see so if someone uses two tags politics & trump that toot won't show cause you have disallowed trump tag
(use filters via profile settings will also help weed out things from pinned columns)
