when grid's FilterMode.Simple is used on DateTime column, is it possible to get rid of DatePicker's left column with operators?
Also, there seems to problem with month/year rendering now which is independent of theme. That must be recent because i remember that it was fine some time ago.-- resolved, see comments
It was some hard cache, Clear Application Data in DevTools or Ctrl-F5 didn't helped. Only clearing cache in Ctrl+Shift+Del menu helped and now it's ok.
