let us view the various "Icons" column modes at the same time?

Currently, when a song has been played there's a checkmark in that column, and the icon that would show whether the track is on the preparation list is not visible any more. It's also not visible when the track is loaded in a deck, because there's the deck letter in that space. It would be good if these icon modes each had their own column. Another weird behavior this would make a little more intuitive is that currently, when you switch between the modes, it automatically sorts the browser by the new mode. And in addition, it would perhaps be possible to implement sorting both ascending AND descending for the modes? And including them in the primary/secondary search parameter function? Cause that's not working at the moment.
