Make rando button smaller and add fx/sequencer toggle

The rando button takes up a whole lot of ui space. I personally wouldn’t mind having it a lot smaller, since you only use it a few times realistically. i knows its part of the charm and recognizability of the plugin but it doesn’t have to be this large imo. you could for example also have the sequencer or FX togetherswap open, and keep the waveform open at all times. The waveform also looks good and it gives a good representation of what kind of sound/length your are playing. ALso it makes editing way faster instead of having to cycle through 3 different tabs.
