I am missing, now with MB and previously with MMonkey, the ability to change the values of a single file or infinite number of selected files at once, with just a right click, without it opening a window. If I right-click over genre of say 10 highlighted songs, I wish to be able to change that genre right there. Now regardless of where I click edit, it opens the screen that is saved to the last view-tab, too; it doesn't even take me to the value position of the item I wish to edit, based on where along the screen (over which column) I clicked edit.
In short.. I wish to select a file or as many as I wish, right click over for example genre column, one of the lines/boxes becomes editable, I type in the new value, hit enter, and the same value propagates to all selected files' same column. Windows media player 10 still allows for this (in XP).
