If you have used IBM Notes for any length of time as an end user, you no doubt have come to the point of frustration trying to find that seldom used but all important app or database tile. Or worse, clicked on a tile only to find it is no longer functional because the database moved or the app is no longer supported.
Similarly, application development and maintenance can be a challenge if it is left up to the end user to find, install and manage apps and databases.
