We have also heard feedback on the width in general with the modal and have investigated a better option. We are looking to update the modal so it’s now 80% of the browser window. This largely supports how extension configuration pages worked in the past and would allow the window to dynamically change as originally required.
We will only cap the iframe at 1100px if the 80% of the browser exceeds that to support an easier view of the configuration for streamers on small to mid-sized screens.
We are looking to push this update out tomorrow so it can hopefully rectify the issues most of you are seeing. Again we apologize for the inconvenience and thank you for your feedback.
