这个功能确实很有用啊，比如一边开着网页看手册，一边敲命令，只要把终端设置成半透明+置顶，就可以避免挡住网页文字；再比如同时编辑几个源代码文件，即使屏幕不够大，窗口有的叠在了一起，也不必担心看不见某个窗口的文字。
确实也有终端模拟器支持半透明背景，但是它们的透明其实是机械地复制下面窗口的内容，而不是向 Compositor 请求真正的透明，如果拖动窗口速度比较快就会看出破绽。
找了很多替代方案，最后看好 LilyTerm 这款台湾人写的终端模拟器。
需要的很多功能都有，可配置性非常非常非常强！稍微配置一下就能完美找回 GNOME Terminal 的感觉。
所有的配置都在右键菜单，配置完成别忘记选择 右键→用户配置文件→储存设置 来储存。
下面贴上我的配置文件，位于 ~/.config/lilyterm/default.conf。99.999% 的 GNOME Terminal 习惯都能找回来（包括快捷键）！

P.S. 发现一个很贴心的功能，如果复制了几百行文字不小心选了粘贴，会提醒你是否真的要贴。从这可见 LilyTerm 的开发人员的细心，和 GNOME 开发团队形成鲜明对比啊!（当然我不否认 GNOME 3.8 也带来了很多贴心的小功能。）
