Description

Description:
When resizing the layout to make the main pane wider, the file list on the right also expands and takes a significant share of the newly available horizontal space.

Expected: The additional width should primarily go to the main pane. The file list should remain near its current width, only growing once the main pane is already sufficiently wide (for example, around 1000px).

Actual: The file list starts growing too early, making it difficult to meaningfully widen the main pane.
