Mobincube, like every computer system, has a limit in processing capacity. Therefore it takes long time to load the app in the editor.
If you are having more than 50 detail screens and all they are almost the same (you did them by duplicating a template), it indicates that you could have saved that work using data views and a database. Details views allows you to substitute some texts, images, locations, etc... from the content of a local or remote (you can update them without publishing your app again!!!) database.
Also Dataviews are also very complex and if you are using many of them your editor will have problems to open. Optimize them using dynamic filters and relational databases. With two screens you can have the same functionality.
