Windows Improvement: Group Header Status to Persist Between Views

[Don Smith]

In the Windows version, in a To-Do view, I'd like the status of group headers (open or closed) to be persistent between views, as they are in the IOS version.   To illustrate - a simple example - if i'm grouping to-dos by category and have three categories @morning, @afternoon, @evening. If I open the @morning category group in this view and keep the others closed, then when I click away to something else (eg All Tasks, or another To-Do view), when I go back into my original To-Do view, I'd like to see the view as I left it, with only the @morning category open.   As I said, this is how it works in IOS.   It's a simple and superficial change but actually one that really improves how MLO functions.
