Yes, #1 and #2 are both to better distinguish which item I rather want to paste.
Often I have that many same looking items I can't tell which one is the right.
So #1 will show me the length of the item so I can better guess which one will suit better.
#2 has the advantage to actually SEE what is going to paste in whole (well, more or less) by extending the amount of displaying tool tip text.
IOW: the amount of text in the tool tip is not enough for my needs.

#3, yes, I want to disable some of the menu items which I don't need to "clean-up" the menu and get more room to show clips.
Thanks.
