Wish: finer resolution for scrolling up and down

Hi,
whenever I scroll up and down through the images in an album, I quickly lose the overview because the images don't move up and down smoothly, but jump a to big distance. This is very confusing.
Another screen problem is taking the last picture from the list and moving it upwards in a long row. The movement is either very sluggish, too fast or not at all. Moving a picture down is even more difficult.
I wanted to make a screenshot video of it and scaled down jAlbum on my huge screen (3840x2160) ... and now moving the image is much better and now also downwards.

Because there are so many images (rather than just text), this kind of scrolling is always a problem. To move objects more than a row or two, it's easier to use cut and paste. |

If you're using the scroll wheel on your mouse, the scrolling behavior is controlled by the operating system. You can tell the operating system to scroll fewer lines with each "click" of the scroll wheel, but then it will be slow. It still won't be smooth, because the minimum setting is one "line" at a time. And that setting will affect all other apps on the PC, as well, like your browser.
You can get much better scrolling by clicking and dragging the vertical scrollbar on the right.

Moving image up/down ... it seems to be dependent on the shown jAlbum size. In full screen it's not good working, in small custom size it works better. I suppose so there is an area coded, which control the speed of up/down and this area seems to be optimized for small screens only. Please check it on a large screen.
Mouse wheel scrolling ... oh, that's hard. You mean each photo is a line and so it can't be finer? Is there no way to code it finer? Yes, the scrollbar works good, but it's not so quick done.

I'm on a typical 1920x1080 monitor, so I can't say anything about how it behaves on something bigger. But when I make the window smaller, the scroll rate doesn't appear to change, or if it does, it's by only a very small amount.
I find the scrollbar much faster than the scroll wheel. Using the scroll wheel is like using the arrow keys - it needs a lot of user input to get from top to bottom.

I checked it again and when dragging and dropping up and down, the scrolling starts and accelerates in a range of about 1cm. The range could be larger, perhaps twice as large and a little faster at the end. It also went downwards in the new test, no idea what happened yesterday.
It would be nice if, when you leave the range above the maximum, there was no stop but the maximum speed was maintained.
If it were possible to scroll jAlbum up and down more finely with the mouse wheel, that would be nice, otherwise that's just the way it is.

So you're using the mouse wheel. What operating system are you using?

So you're using the mouse wheel.
The mouse wheel is a very crude device, in virtually every application. It's bad in a browser, a word processor, or a text editor. But with a window full of images, it's really awful. Just try it in Windows File Explorer, when it's displaying "large icons," i.e., mid-sized thumbnails. This problem is not unique to jAlbum.
There's nothing smooth or elegant about the movement, and it's tough to keep track of where you are. The mouse wheel is OK as a means of quickly moving up or down through a lot of stuff, but it's a sledgehammer.
In short, this is one of the great unsolved UX problems, even after all these years. |

I've now made the mouse wheel scroll speed configurable for jAlbum's explore view in jAlbum 34.1. See See https://jalbum.net/software/release-notes
(The problem is that one can't distinguish a mouse wheel operation from a touch pad scroll gesture and there is no ideal setting that suits both usages. For that reason it's better to allow the user to configure this setting) |
