• If a feature you're looking for is not available on the site, you can vote to have it included. Better yet, if you've done the research you can even submit it yourself!

• You can import usage data from your Google Analytics account and see exactly how well a feature is supported among your own site's visitors. Look under the Settings panel to get started!

• Usage data for all countries and continents can be imported via the Settings panel.

• By default, older browser versions are only shown if they have >= 0.5% usage share. You can increase or decrease this value from the Settings panel.

• Each feature support table includes a "Usage relative" button. This will resize each browser version cell to be relative to the amount of support it has for the selected usage source.
