Everything is running smooth, nothing major to report so far just some cosmetic stuff..

1.
Yes, the image is cropped.
There is no other solution for this format.
And it doesn't look bad.
If I were to do what you want, I would have to rewrite everything, that would be too much effort for me.

2.
What is double for you? 
Please show me example screenshots. 
Unfortunately I don't know what you mean. see image1

3.
"Prefer fanart in landscape views"
This setting works. see image2,image3

4.
The tags display works as it should.
The only error is with "Square" in connection with program addons icons, then the tags are displayed twice.
Once as an overlay and once under the icon.
But that shouldn't be a problem because you can deactivate the tags under the icons in the side menu.
I will fix this in the next update.

To ensure that overlay tags are no longer displayed, you need either a landscape image or a fanart image + a clear logo.
So if you only have fanart images for your movies or TV shows you will always get these 2 day ads.
The reason is simple because all landscape images show the title, you can deactivate the tags for this view.
And if you have a movie without a landscape image and clear logo, the title will be displayed as an overlay tag. see image4
