what i just do is have a single (empty) pattern which is, say, 48 lines, then copy that 30 times, then work inside that. of course when you go switching between patternlengths that won’t always work.
Ah! Thanks @dblue and @rhowaldt! Two ok techniques that I didn’t even think of myself.
It would be nice if there was a shiff-control-right-click (or whatever is available) to create a new pattern with the same pattern length as the current one. Just sayin’…
