• add some shortcut like "Ins" for add watch
• put a second (third, etc -- VS has Watches 1 to 4) watch window
• if there is a variable that is not a primitive and has hierarchical
  contents, if I look at some value say a.b.c and expand the view down to
  a.b.c, it collapses back when stepping, and that's annoying. The
  collapse didn't happen on 3.2's Local Variables, but it happened in
  Watch on all versions, and now in 4.1 seems to happen in Locals too...
• don't know why, but expanding is kinda slow (1-3 seconds for 4
  subitems, 20+ seconds for 50+ subitems). this didn't happen in 3.2, it
  was instant
• allow to 'edit' an entry, if I mistake a letter I have to remove it
  and add it again...
