I've only looked at the flat version.

The top-level package will be MiniBrowserflat - in a conventional installation this directory would be a sub-directory of site-packages. The main script (minibrowser.py) is not part of this package even though in this case it is in the same directory. Therefore the import statement in minibrowser.py should be...

from MiniBrowserflat.mainwindow import MainWindow

For the same reason the import in mainwindow.py should be...

from .Ui_mainwindow import Ui_MainWindow

This will deploy properly. However it will no longer run normally - unless you set PYTHONPATH. To get it to work unchanged in both circumstances move minibrowser.py to its parent directory so that it is side by side with the MiniBrowserflat directory.
