I have a LOT of sports that I record and then try to organize. I made a dedicated list for "sports" and then grouped according to the type pf sport: "Skiing", "Cycling", "Baskteball", etc.
I love details view and I love the flexibility of sorting/resorting according to column headers, and the ease of rearranging columns. But there are TWO THINGS I'd like to enhance about this setup:
1. I would like to "Group" within a group. I know I can sort within a group, but in details view I cannot nest a group within a group. In the group "Cycling" I would like to add the groups "Road Cycling" and "MTB". Within the groupd "Road Cycling" I would like to have groups for the Grand Tours (TDF, etc) as well as minor races. This would cut down immensely in the organizational clutter.
2. I would like to be able to collapse a group in details view into its own title bar, with a clickable expand/collapse arrow. This is exactly what was done in a now-defunct competitor to MC, and possibly for that reason it has never been considered, even though it would only enhance and clean up the details view interface.
For another example of how this might look, imagine you have DVD rips for 4 years of Game of Thrones, along with recording of the most recent season. In details view, that's just going to sit there are one long list of 40 or 50 files, grouped under "Game of Thrones". But how about a sub-group for each season, collapse into their own title bars so that you could immediately go the the season you wanted to view?
Again, this all has to do with Details view, and extremely powerful layout that could benefit from these very easy and unobtrusive shortcuts.
