The new button to switch between grid mode and multi-line mode is great! It's making my life much easier. And having the Note button in grid view to show/hide notes is great too. Now that I have these options, I normally use my task list in multi-line view, with details hidden. When I want to see the details, I click on the Mode button to change to Grid mode so I can see the details all on one line, because it's easier to find or sort by a particular detail that way. So now, I only use Multi-line mode when I have the details hidden to get a less cluttered screen. This works great! Best of both worlds. Thanks to TD for this great improvement in the UI.
I suggest you add an option to have the "Notes" icon there all the time, whether in Grid or Multi-line view. So even when I'm in multi-line view, with Details hidden, I could still click on the Notes icon and see my notes, without having to switch to Multi-line view to see them.
