I would install the other version, since they're currently at parity, and the flathub version takes more space.
我用linux mint 20.2,进行了中文相关的设置。在软件管理器里安装这个软件后(软件管理器里的软件名是“字体管理器”,0.8.7 )后,界面是英文的,安装另一个软件“FontManager”(0.7.7-0.3)后,界面是中文的。这两个软件重要的是可以直接将windows中的fonts文件夹拖到“preferences”的“Sources”中以添加新的字体源。Ubuntu Kylin里自带了这个软件,我在那里用过这个功能。
It's better than the other version on here, but it crashed on me. Also, I've no idea what the functions of most of those settings are.
