When i open too much firefox windows it goes out of the screen and no scrolling is available. Maybe i can configure windows preview size when hovering cursor on the task manager icons ?
Or make scrolling via the open windows works with mouse wheel?
I think the answer here is to use grouping and Firefox tabs to keep the number down.
Otherwise change the icons only task manager to, or add, Windows List.
Well fix the scrolling with mouse wheel or scroll with hovering the edges of the preview pane is overfeauture ?
I suspect you’re running into 463054 – With horizontal panel, wide scrollable Thumbnail list not scrollable with scroll wheel on Wayland.
