I don’t think this has been published before here. If you’re fed up with big blue bar numbers in galley view and want to have nice and un-cluttered little blue numbers instead, here’s the tip :
• Make sure you know what space size you use.
• Create a system/frame break at the very beginning of your music. Select it in Engrave mode, and in its properties, input the space size you have checked in step 1. This will ensure that your layout will not suffer from next operation
• In Layout options>Page setup >space size, choose rastral size 0 or 1.
That’s it. Your galley view will show bar numbers at a very nice size.
Hope it helps !
