Adding individual entries from the simple user interface (SUI) menu to the right click context menu of the avast icon could make the list very large, especially when you add other peoples wish lists.
However, adding a link on the avast icon for the Simple User Interface 'Menu' would give much quicker access to a number of options that there like the Settings, Schedule Boot-Time Scan, Virus Chest, Virus Database, Log Viewer and Help. All of these options don't really require the running of the memory check and opening the SUI just to access them.
