Just tried this, on the off-chance that it was already implemented, but it wasnt…
I would love to be able to double click the divider between the Pattern Arranger and the Pattern Editor, and have the Pattern Arranger pop to maximum/minimum depending on its initial state.
Would make viewing the names of patterns on the Pattern Arranger and then closing them again a lot less clumsy.
Of course this could be implemented on top of the already present click-drag method…
