Every time you interact with an element in Adobe Express the menu on the left side of the screen tries to open to the applicable editing tools. The issue with this is that as you're trying to grab different objects to arrange them on the page the menu is continuously trying to open and close which is also shifting the work area, making it very hard to move elements as needed. I'll attach a video to show what I mean.
I think opening and closing the menu should be a manual option. It should stay closed until you re-open it. This would make using the application way more friendly, and would reduce my frustration by a million percent.
