As a Roblox developer, it is currently too hard to know the orientation of a part or attachment. The current move ui shows three sets of arrows, but the same colored pair (front and back for example) they look identical. We cannot readily tell which is back and which is front.
If Roblox is able to address this issue, it would improve my development experience because it would save us time from keep doing the adjust>play>adjust process.
(my current personally experience with it is like plugging in usb into the ports, where you have to flip it back and forth to find the correct orientation )
