In fear of sounding "naggy" I'm still waiting to hear some thoughts on this:
Would it be reasonable to open a bug on the My Presets/My Samples browser?
The search feature only works for folders that have been expanded and is quite unpredictable (i.e. once expanded and collapsed the search still works for that one folder, but refreshing breaks it again).
Secondly, is the "create new project from template" button in the toolbar unfinished at this point? It doesn't appear to be functional, at least in Windows.
Lastly, would the project consider some recommendations for re-utilizing some vertical real-estate? I have some ideas I'd like to propose.
