X3Photo Gallery Forums

I think what you are asking for, is basically what we have for our new Files app. See the demo:
https://demo.files.gallery/?balloons

It's much faster, allows you to use full browser width, and menu can be collapsed. Additionally, there are "filter", "sort" and "layout" mechanisms that allow you to optimize the view in real-time. Files app will be used as foundation for the planned X3 panel 2.0, which then will deliver what you require I guess. Until then however, there won't be any modifications to the current, somewhat outdated X3 panel.

Is there something I did wrong, or will there be a solution in future?

I don't know when you tried X3 panel last, but it has definitely become faster through various updates. With X3 panel 2.0, it will be much faster, although there will always be a delays proportional to the amount of folders and speed of server. Files app uses will use cache though, so it will only reload menu when you make changes. Also, a way to circumvent slow loading folder-menu, would be to set a maximum "depth" for the menu (for example 1-3 levels). This way, the menu won't load the entire structure, but you can still navigate to deep folders directly from the main layout.

Not yet. I might say first quarter 2021, but I am also considering a major X3 upgrade (X4?), in which case it might take longer.
