Webflow's Responsive Image option is cool and provides additional flexibility in many situations.
But it requires a keyboard shortcut to trigger it, which is very unfriendly; and it's also hard to remind myself and other colleagues of this option.
Suggestions:
Display the "Responsive Image" option by default
Put the "Manually generate responsive images across a project" option in Designer's Settings
( I wonder why these options are developed but have to be hidden... )
FYI, currently, it works like this:

Disable responsive images
You can disable this feature for a specific image by hitting CMD+SHIFT+O on Mac or CTRL+SHIFT+O on Windows, then clicking the checkbox that's revealed in the image settings panel.
Manually generate responsive images across a project
Hit CMD+SHIFT+I (CTRL+SHIFT+I on Windows) and the designer will scan and re-measure all your pages for you.
This is shipped around a month ago! finally...
