Description of problem: For UI consistency across all IME's and better user experience, it would be nice to list all the input mode options under one tab. e.g ibus-libkkc has "Input Mode" option under which all input mode have been listed. Similarly pinyin could have "Input Mode" under which "Half Width Letter,Full Width Punct,Simplified Chinese" options.
Only the first property is about input mode. The rest three properties are normal toggles, which can not be grouped into input mode.
