***


STEPS TO REPRODUCE
1. Open Discover
2. Click "Installed" tab
3. List of installed packages can only be show by size and order

OBSERVED RESULT
Working as intended.

EXPECTED RESULT
Not what I expect, what I wish.
Nate told me to create this bug report.
Discover works just fine to install and remove not programs, but does a poor job in managing those installed programs. Sometimes I want to remove something use Discover and have to browse thorough extensions and themes, and icon sets and other minor things, or the contrary. Would be better if there there options on Dolphin's interface to filter those results, more options. It could group the results in collapsible categories for example, filter by Flatpak and DEB, for example.
