Congrats on the upgrades and updates, site slowly getting there, now might be even faster.
Just some constructive suggestions from my side:
- I would put the Dark theme as default for everyone, even offline visitors as it is the preferred style as seen on your OP images.
- Wouldn't it be better to order the Platform list alphabetically?
- In my profile, I would put Favourite games on top followed by the wall and move recent activity plus recent forum posts to the side.
- Just a last comment, I thought the theme selector on your account dropout was an error, it's functional but not clear what it is at first glance, maybe mention theme?
EDIT: And just seen that the quick reply text box is still white in the Dark theme.
And just experienced that you can paste directly an url image and the editor embeds it for you, cool
