It would be really useful for front-end users to be able to resize and dock/undock some of the widgets in Experience Builder, so that they can change sizes to better suit their screens. For example, the table widget docked to the bottom looks fine on large screens but on small laptop screens can be too small for them to even be able to scroll through rows. I can increase the table to e.g. 50% of the screen, but this takes space away from the map. So if the user could control the size of the table themselves it would be much more user friendly.
I can see this being useful for some of the other widgets too such as side bar, feature info, survey, chart, and probably others.
