Don´t focus on text on mobile
Mobile version: When typing on the text fields on the canvas & and type into the text area the window zooms in. But this is not required. My customers must see the design change while they are typing.
A setting for deactivating the "auto focus zoom" would be great.
You can fix that with CSS by setting this text input font-size to 16px.
