I don’t get the first point. ‘Frame’ here is used as a verb.
‘Viewport Render Image’ is indeed better than ‘Viewport Render’. We should fix this in the 3D View too.
Re. Play: I think we should remove this from all the editors. It’s not a view setting - it’s just playback, and you can see the hotkey if you read the tooltip on the play button.
The main thing is just consistency above all. If we change the name of something, we should do it globally, not differently for different Editors.
