Yahoo! Inc. (NASDAQ:YHOO) Chief Executive Officer Marissa Mayer has been making a lot of changes at the company since taking the helm, and we’re about to see another one. She’s planning on giving Yahoo! Finance a makeover. This includes both the desktop site and the app, and some users of both are a little bit concerned.

Concerns about Yahoo! Finance changes

Chris Ciaccia of The Street voiced his concern about changes to the desktop version of the popular feature. He said although some minor tweaks would be good, he hopes there won’t be a major redesign of the entire site. The only things he feels would help the desktop site is more white space, more interactive charts and a slight cosmetic facelift.

Overall though, he doesn’t think the desktop site needs that many changes and would like to see it largely remain the same.

Overhauling the Yahoo! Finance app

The one area he believes needs quite a bit of help is the mobile app. He expressed a desire to see an app which looks like Yahoo! Weather. The weather app was redesigned not too long ago, and he calls it “extremely attractive” and says it “provides data in a way you want to see.”

Mayer has been largely focused on honing Yahoo! Inc. (NASDAQ:YHOO)’s mobile sites, so it would make sense that the mobile app would receive the biggest makeover of the two. She has expressed plans to monetize the company’s mobile offerings, and Ciaccia believes a redesigned mobile finance app would be very helpful to Yahoo and its users.

Other major overhauls at Yahoo!

Earlier this year Mayer said Yahoo! Inc. (NASDAQ:YHOO) would make major changes to its search results. The company is trying to cut down on the gap which exists between itself and Google Inc (NASDAQ:GOOG), which holds the largest share of search by far.

Yahoo also recently shut down a number of its apps, including Upcoming, Yahoo Deals, Yahoo SMS Alerts, Yahoo Kids, older versions of Yahoo Mail and Messenger feature phone apps. The company plans to unveil its newly redesigned logo next month.
