Vimeo's Feature Release
Vimeo recently released a few new features using super simple modal windows. Here's what they look like:
What we like: this feature-release is concise, simple, and effective. The transparent background prevents users from being distracted by the announcements, the progress bar provides an "end in sight" and motivates users to stay engaged, and users have the option of opting out at any time. Plus, each modal provides informative text and example visuals.
