QuickMark is an Amarok script that allows you to set and recall Amarok's current file and position from the context menu.
In the playlist context menu, use the 'Set Mark' entry in the 'QuickMark' menu to create a mark in the player's current position. Once set, a mark will appear in the bottom of the 'QuickMark' menu.
Selecting that mark will cause your player to return to the position it was in when the mark was set. If the file you saved the mark in is no longer loaded, it will be added to your current playlist. Use the 'Clear All Marks' entry to clear all marks.
