Poorly designed, cluttered interface, marginal performance

Very poor interface. App is poorly designed and clutters the screen with multiple windows. During a call, one window remains constantly in the foreground preventing you from working with other apps. For example, if you’re talking to someone and discussing a spreadsheet, this foreground window will obstruct your viewing the spreadsheet. The dial pad must be clicked with a mouse, it won’t take input from your keyboard or keypad. Very unfriendly and unthoughtful interface. I’m uninstalling it from sheer aggravation.
