is there a way to link topics?
with # and name I can link streams but unsure how can I link topics
AFAIK you just need to copy a permalink and then use a standard
[name](url) Markdown link.
I see there are a set of linkifiers here https://rust-lang.zulipchat.com/#organization/filter-settings
maybe worth defining something for topics too
Don't think you could, the link isn't predictable, they always have an id before it.
