The New In-Game Topbar is an amazing design, and I can’t wait to see the design coming in Roblox! I also liked the modern looks on the Topbar. Both of the versions (Old & New) of the Topbar is also nice too! 
I hope to see the New Topbar coming in the update. Keep up the great progress! 
I like this change. I do prefer the old leaderboard, though. This change does make it more modern.
Also will this be changeable in studio? Like the custom ones in games, for example vehicle simulator.
It will open the ESC menu. Just a guess.
This is actually an awesome change! Thank you for implementing it 
Awesome! The Roblox UI is getting better, however I still have to get used to it. 
The next release is a modern chat UI?
Not all really know the short-key for for example open the Inventory, so it should help if a it not know or have forgot it.
im excited for this! i will miss the old one. but im still excited … or how do we say? EGGCITED
The only topbar update I would want is the removal of it. This topbar feels even more intrusive than the old one.
EDIT: This felt pretty unconstructive so I thought I would give my reasoning.
Best case scenario I do want the topbar removed or at least give us the option to remove it. I know this most likely will never happen, which is very irritating to me.
The topbar being transparent for every game will be a nice change in my opinion. I am happy with that change.
The thing I am not happy about is the Roblox icon. With the old topbar I could remove everything except the hamburger icon and the age indicator (which seems to be removed now!).
The hamburger icon felt more minimal and out of the way. The Roblox icon looks unnecessarily big and a branding mark on your game.
I hope this clarifies.
It’s nice, I just personally think the old one gave more life; it just looks a little bit empty and quiet.
I definitely prefer this new version to the Topbar. I personally dislike that solid black banner spanning the top of the screen.
Though there are some things I would like changed (such as the button at the top right of the screen), I welcome this change.
Does this change have anything to do with disabling the bar in studio? A while ago when I was turning it off with the CTRL SHIFT G combo, it stopped working with that combo when I would take immersive screenshots and stuff. Still unknowing of how to turn it off as of now.
I hated when top bar was first added because it looked hideous and wasted 36px of space for no reason.
With this update making it more minimalist by default, I finally won’t have to look at its terrible design ever again!
Good job.
Edit: I don’t care if it feels empty, it means more screen area is free for developers to use and players to see.
I like the simplicity. Simple but clean. :))
Oooh! I really like the new top bar! Looks super clean! 
Is would be a great change I personally really don’t like the current top bar it takes too much space and when you have the in game performance stats up it takes up even more space. (I mainly use the stats when playing Phantom Forces, to monitor my internet stats, and it’s annoying when switching weapons)
Looks great in the screen shots, would there be a way to maybe customize colors? Or even size.
Another question, is there still technically a topbar but just transparent or not as big. From what the post said it seems like it’s still there.
I remember the days when there were no topbar thing, it was nice.
Very nice and clean, definitely a good addition to all games!
I don’t like it, kinda.
I always preferred making my topbar opaque but now it feels more weird. The icons feel weird and if the topbar does not follow the same old 36 pixel height, it will make custom topbars useless (unless fixed or changed).
However, it fits well with the new UI, and I’ve liked the rest so far. I hope there’ll be a topbar transparency you can set like before, so I wouldn’t need to play around with a custom topbar.
Making the game modern, just make sure you don’t remove features while doing it! 
Very cool looking and looks much more clean but i still like the settings as the three lines rather than the roblox logo.
But I still want the old leaderboard though!!!
At least make it an option that we can change how the leaderboard is.
I see a lot of issues with introducing this so first I must ask other questions…
