I used the extended UI with the settings at "More aggressive".
Then I switched to the simple UI and when clicking "Clean and fix..." I got the warning message about using the aggressive mode.
In the simple UI you can not change that because you can't access the scan settings, so you have to abort.
So, after switching from the extended UI to the simple UI the settings are kept as they were before.
Question: shouldn't it be better to return automatically to the default normal setting when the user switches from the extended to the simple UI, or is the actual situation by design, i.e. the settings choosen in the extended UI are kept when switching to the simple UI? Maybe that's easy for the advanced user who previously chooses his settings in the extended UI and then switches to the simple UI so he has afterwards only have to click on "Clean and fix..." to start immediately the cleaning mode he prefers.
