While investors anxiously wait for Twitter to name its next CEO, the social giant continues to refine its various offerings.

Vine, for instance, just got easier to navigate, as well as a new HD broadcasting and viewing option.

“A new list of suggested Viners makes it easy to find more accounts to follow,” Kristian Bauer, a engineer at Twitter’s video unit, writes in a new blog post. “Simply tap the Find People icon in the top left corner to see hand-picked suggestions.”

To take advantage of the new HD quality setting, users need only tap on the Settings gear from their profile page, and then tap on “Your Content” to see new options.

Earlier this week,Twitter announced new beta features for app install advertisers. The ads let users download apps just by clicking on them. However, investors and advertisers, meanwhile, are far more concerned with Twitter’s CEO search.

“The next CEO needs to innovate and do a much better job of serving both users and advertisers,” Forrester analyst Nate Elliott recently told Social Media & Marketing Daily.

Among other attributes, interim CEO and co-founder Jack Dorsey wants his replacement to live and breathe Twitter. “We’re looking for someone who uses and loves the product,” Dorsey told analysts on a recent conference.
