Icons to expand and collapse panes in multi-processing window too small

[a-s-russo]

Is it intentional to have the buttons highlighted in the image below so small? They are very hard to click since they are so small, and I suspect many users miss seeing them because they are so small, especially in the latter image.

These icons are part of the FlatLaf look&feel used in the NetBeans Platform. We cannot change these icons easily. See https://www.formdev.com/flatlaf/components/splitpane/

Thanks for explaining @charphi. Based on the link you provided, it seems SplitPane.dividerSize might help? (Or perhaps that doesn't scale with the arrow icon size, and only changes the divider size but not the arrow icon size, as you seem to have pointed out to me in your reply.)

Otherwise, no worries if this is problematic to fix.

Note also that I think this issue is better classified as an 'improvement' rather than a 'bug'.
