Possibility to disable islands or chains of patterns

[Gimber]

Not a problem, it's just not compact on the screen to always leave empty row every 2 rows.

But it is not a big deal, I can continue like that.

Thanks

Would using BRK100 at the end of the patterns eliminate the need to do this? 
I used to have lots of empty rows when I used brk000 all the time, but it's less necessary when using other brk values.
