For heavy hashtag users, is it possible to hide hashtags from blocks but show them on mouse hover?

Hi Unless there is particular reason you want to use hashtags you could use page links [[hashtag]] instead of #hashtag. The two ways of linking are not distinguished in Logseq, so I usually use the former in text, and the latter when adding a “tag” to a block. See The difference between [[page links]], #tags, and properties::.
