That is great they made a tweak. An optimal tweak would be that when we drag a group onto the canvas it has a min height of 20px and min width of 20px with no max width or height.
When we have elements selected and use the group in a container there should be no min height and no max height with default to fit height to content. It is very annoying and jarring to group a text element with 16px font size (so only 16px in height as an element) to then have the new group it was grouped into to be much larger; 40 is less than 60 which was less than 140, but still likely even at 40px will cause many many developers to need to change it.
Seems like consensus has been 20px or less…I’d say do not do less as for new users if they drag a group onto the canvas they still need to see the group as there and have a dropzone, but anything about 20px is likely still not getting to the root of the issue and the requests.
