I just noticed some fairly experienced users don't seem to know this (making for some unnecessarily long formatting), so I'm making an article to share this knowledge. If you use shift+enter to create a linebreak, it's smaller than the ones created by just the enter key alone. This is useful for when you're adding linebreaks for the sake of lists (such as having your character's tags, an accessory/alternate mode, and recommended negative tags on separate lines in a LoRA description, or listing a class of tags in an article) instead of a new paragraph. The only con I'm aware of is that the header formatting considers lines separated this way one line.
