It seems that it's currently not possible to replace item bullets by some custom icon, for example by an right arrow. I could imagine two configuration variants: replacing all item bullets of one level by the same icon or just replacing an individual item bullet.
I tried to work around by inserting hard line breaks, but this only works for the first plus sign (the others do not produce line breaks). What am I doing wrong?
* bla
* blubb +
=> result 1 +
=> result 2 +
=> result 3
Best regards,
