Bleachbit (no scaling down at all):
Scrollable, but can’t view the right-side frame:
Possible to see everything in landscape, and fully scrollable:
Preferences screen also good:
Even in portrait:

PureOS store has 2 versions:
Bleachbit and Bleachbit (as Root). I chose the non-root version, but root version also installed as a separate app. The root version failed to launch…maybe because the default L5 account is non-root.
