Problem is actually that it isn't displayed in your client as an @, not that it doesn't work as a mention.
Tagging from a list is nice, but not really as high-priority as other features, since we can just use other clients for that.
feedback like this is so important. evaluating what the most important next thing to work on is really hard at the best of times. especially so when having to 'wear every hat' in the software development process.
Do you mean that an inline reference to a users like @Laeserin should render with their name instead of long npub displayed as text?
Yes.
Ask and you shall receive. Implemented in commit 44fb751eca41de2859562a724ac9a567080a75d9
There is more of a dopamine hit when there is one issue per feature. There is like 6 other things to implement before this issue can be closed.
