I'm also guessing my forum username is based on the portion of my email before the

@

but you'll want to exercise caution because I'd guess that's not as unique as one might think

i just realise there is no way to change it (for now)

True. I was hoping the username can be changed.

Thanks for the feedback! I've added it. You can update your display name in the profile. You can access it by clicking on the avatar in the top right corner.

That is not my experience; is there a way to formally report bugs, or posting messages here is still it?

We're open source and code is in github, so you can create an issue there, or we can just follow-up here. It would be ideal if you could add a movie or repro steps!
