yup, I get it... But these are more a conversation options (and behold, they are listed in a conversation window
)... The right-click menu of a floating contact shouldn't contain any specific conversation-options/tools/features. Otherwise, where do you draw the line? Adding ping? ok, what about adding all the emoticon sounds, the plugin commands, or share file menu, etc.... do you know what I mean? The menu will become very bloated very quickly. Furthermore, it is equally quick to simply double click the floating contact and type /ping (or your quicktext for that matter)....
And sure, maybe you use the ping command a lot, but if you look at the avarage, then /ping isn't used that much though.
