Hi Oliver!

www.rusterholz.me, with a slideshow as a frontpage and more or less nothing else. I have a scroll bar on the right side, is there any possibility to get rid of that?
This is a complex matter, because the scrollbar is part of the OS (operating system). For your info, there is no visible scrollbar on Mac, or mobile devices (obviously). So the issues comes down to
Windows OS and different browsers. What OS are you using? I thought perhaps Windows 10 already did auto-hide scrollbar, or perhaps it's a
setting. But then there are differences across browsers ... There is a new
-ms-overflow-style CSS style which allows us to control it in the browser, but this only works for Internet Explorer.
The answer is therefore, probably not. There might be room for improvements.

This is not an option, although it can be fixed with custom CSS. I'm not actually quite sure why I made it like this, but I'm pretty sure it was something to do with keeping menu's symmetric. Obviously the second level dropdowns would have to match the widest width, else the width would jump when hovering the parent menu's.
To make the 1st level match it's own widest element, add the following to
Settings > Custom > Custom CSS:
.menu > .has-dropdown > .dropdown {
min-width: auto !important;
}

So that I have an album of e.g. my vacation with regular stuff and then hide the pictures in this same album with people in it and show those pictures only logged in persons without creating a new album.
Unfortunately, no. In X3, page output will always be the same, regardless of user/login. Many reasons for this, including caching, SEO, and how X3 creates galleries from images in a folder ... More importantly, it would require an intricate user-system, where you can select each-and-every image and assign them "visible" or "hidden", from multiple users. Maybe in the future, but now this is not a feature.
Thanks!
