As the initiative count goes up, the Strategy -> Initiatives screen becomes less and less useful due to the lack of filters. I see two improvements that would make this feature much more useful to customers that do significant planning (which reports views do not help with):

1. Add some filters - Ideal would be similar filtering functionality to Features. Give us everything. Too hard to pick a limited set of off-the-shelf options that would meet everyone's needs outside of Status and Timeframe. 
2. Consider other ways of presenting initiative information. Columns with drag and drop would be very nice, similar to functionality many companies are adding to planning tools. Ideal would be to support selecting a field which provides the value columns would be based on (e.g. Status, Timeframe, a custom field) and update that field as cards are dragged/dropped between columns. We'd love this on the features view as well (as an option to switch from release-based view to any other field-as-column, or at least the standard fields, such as status, etc)
