My wish is trivial – more choice over the width and colour of the playback. cursor - for accessability reasons if for no other reason.
…and perhaps a more joined up approach to import and export of color schemes, settings and themes - there is a lot of individual tweaking that still has to be done.
They are both still amazing products. I suspect some more recent DAWs maybe pay more attention to these points which after all are fairly cosmetic rather than functional. Still user interface is important too.
