My vision has been declining as of late. Unfortunately, I have got a rare disease that is not fully correctable with lenses. I'm now using a larger mouse pointer in Windows.
For the same reason, I also struggle with navigating my media collection in JRiver Media Center, in particular, scrolling through it.
I found the option to in Tree & View -> List -> Enlarge scrollbars on mouse over.
This unfortunately remains problematic, because one needs to first place the mouse within the small scroll bar area. With a large mouse pointer, this is not easy to do. But even if one succeeds, there is also a delay before the scroll bar converts to a larger one, and if you start scrolling before that delay passes, the scroll bar does not get enlarged. And if you haven't clicked, but move your mouse slightly, it reverts to a narrow scroll bar.
I think there should be an option to make this permanent, rather than mouseover. I realize there are several media applications that use custom smaller scroll bars (Qobuz comes to mind, unfortunately), and JRiver is not alone in doing that, but this is still really problematic. None of us are getting any younger, and this can affect everyone.
I know from searches that this change has been requested in the past. Hopefully, this is not too much work.
If this could be enabled through a skin, I would be happy to use one, but it doesn't appear to be possible.
While they are not as pretty, and would look out of place with the rest of MC, the default Windows scroll bars are more functional, and many frequently-used apps such as web browsers use them. Having a "bland" skin that uses these instead of the custom bars would also be fine, if possible.
I have tried Panel, which allows using Media Center through a browser, and thus displays the larger system scrollbars. Unfortunately, Panel exposes a small subset of the native application's functionality, and is not a substitute for it.
