me, i like roundness. i like max5 A LOT more than max4. And i even would love to have rounded multisliders like in TouchOSC. But seeing his personal art on his web site (nice!), i understand that pelang prefer rectangle looking, and in fact, even more personalisation, to lower or increase max objects roundness, would be great.
…I would put "full" roundness, all rounded shaped on my screen.
Year, i'd love to see my patches looking like hunderwasser buildings! :D
