Not sure I understand the first question, but if the topic itself contains "!", that's fine by the app, as long as it doesn't use the characters that the OS doesn't allow (like slashes). The vertical bar syntax is also supported, so you can write [[Topic|display name]] and "display name" will show. I usually leave punctuation out of the link, like `[[name]]'s`. > Also do both types of links provide the same affordances? If I write [[Topic]] vs [Topic](topic.md) is there any semantic difference? No semantic different. UX-wise, right now [[ auto-completes from the list of files in your folder, whereas [Topic]( doesn't.
