One last: You can sort the mpd playlist with one click on a table-header in the playlist-tab. This is great, but dangerous, because normally with a click on a table header only the display-mode of a table changes. Behind the scenes the program does nothing about the data.
What if you run ario on a party with a handmade playlist, which does no run on random-mode, freely accessible to everyone, to add music to their liking? People who aren't familiar with ario (and most people aren't I think) could accidently resort the whole playlist with no chance to recover it apart from a saved copy.
Fortunately this never happened to me... but it could.
I think the sort-options should better only be accesible through right-click in the playlist or on the table-header through a menu.
