theme file
# maximum size of tool bars in tools (0 = no limit)
# if more tools than allowed by height,
# next and prev arrows for scrolling appears
toolbar_max_width = 20
toolbar_max_height = 0
Previously, the toolbars were always wrapped at the defined width.
In the current developer versions, wrapping only occurs when the window is narrow. It does not wrap after the specified 20 buttons, but after 19 buttons.
I found the previous behavior with the fixed break more pleasant.
Should be fixed in r11476
r11479 works
thank you
