In non-game web applications, one of the problems in User Interface (UI) design is that not all users will perceive the UI as easy to use. If the users are unable to perceive the UI as easy to use, problems in user experience may arise, this is especially so for users using web applications for cloud-based chat and collaboration web services. In order to tackle this problem, this study will identify if the freedom of the user to customize his/her own UI is proportional to the user's perceived ease of use (PEOU) of the UI. A random sample of 50 participants aged 15 to 35 years were invited to use Dropbox™, Google Drive™ and Microsoft's OneDrive™, before being interviewed about their individual user experiences for each menu interface type. It was found that the ability of the user to customise own UI is linked to the user's sense of control over the UI. Since the sense of control over the UI is illustrated to directly impact perceived user efficiency levels, it is highly likely that the customisability is proportional to user's PEOU of the UI. Thus by developing a software that can allow both developers and users to collaborate and cooperate in the creation of user preferred UI design would be able to enhance user satisfaction.
