Totally agree... Connect is an easy way to view the software that you own, but it would be nice to hide old versions and/or versions/programs that you no longer use!
Furthermore, some programs that I use are listed under "Your collection", but some programs which also are installed on my PC are listed under "All" with a button to install it !?
So, Connect works, but not yet completely satisfactory...

I would appreciate an option to remove (no longer show) older versions of software adquired, that now still appear in the Ashampoo App.

We introduced the archive function for this purpose last month. It is currently hidden in the small menu under the program poster in the collection.
This allows products to be archived so that they are no longer displayed in the collection.
We are still working on improving the display.
Best regards from Rastede
