Hello,
Emacs26's child-frame feature is very useful. I have created a candadite menu of
chinese input method with its help, and find that it is much fast than popup-el's menu
and comparable with minibuffer.
the only problem I faced it that: I only need show 2 lines with child-frame while its mini
size is show 4 lines, anyone suggest how to deal with this problem?
