Sorry for the misunderstanding. You can delete all the entries from the [Installed application] section if you need. It will not affect the installed packages.
You can remove applications directly from the system. Open the System Designer section, click Installed applications in the [Applications] block, select the required application and delete it.
Please note, the selected items will be removed from the whole system (not only from the section).
I don't want to remove the application, but only selected entries from the list. I have dozens of entries for the same packages, which were uploaded from the development environment along time. I would like to keep only the most recent entries of each one.
