As a Roblox developer, it is currently too hard to move a non-current camera into the correct position. The current workflow for something like a ViewportFrame or ThumbnailCamera is typically to move the current camera into position and then clone it - if it doesn’t look good, move the current camera and clone it again. This process can be fairly time-consuming, and it could be dramatically simplified by just allowing developers to move and rotate cameras with the dragger tools.
If Roblox is able to address this issue, it would make the creation and positioning of cameras significantly easier.
