It would be very interesting if we had the option of ignoring an application that does not wish to install. I, for example, have several applications that I will NEVER install.

That way we could access the catalog of applications and figure out just new applications available.

Today it is very difficult, because we only have the flags "Installed", "Updated" and "Not Installed". If we want to know if you have new application available, we need to look at all the categories and review all applications are not installed, ignoring those who do not want.

In the "LiberKey News" there is always a notification when a new application is available.
So after you have decided whitch applications you want to install you just have to wait until you get a notification that a new application is available.
