I'm rather new to this, so I might have missed something, but I think it would be super helpful to have a mobile device display on tasks (including the automatic changes mobile browsers make to fit screen dimensions) so that you can see how it will look without having to go back and forth into task preview > open your browser debug menu to see how it looks > going back to edit it > then repeat.
Alongside this, it could be helpful to maybe edit your task object layout/size for specific devices. For example, the included objects wouldn't change, but you could change the font or object size specifically on the tablet display, and then choose a different font and object size for the laptop display so that it's equally readable on both.
