Adding new prefs looks like it could be annoying, but there may be a couple of other ones that could be re-used. I repurposed one of the prefs to change the top & bottom margin of bookmark items.

The single row multirow toolbar is neat.It can be avoided using a combination of the multirow and margin options as above. ❓ I would like to know if users prefer having the option to scroll when using the multirow option.

Solution: Use the option to fix incorrect height with a non-zero margin size (see 2nd option tab).

The toolbar behaves strangely when using the multirow option with a non-standard favicon size.

The fixed height option should be used when the multirow option is selected, otherwise the toolbar will try to stay at single row height.
