 ### TODO
-+ Export all messages to libchat, and render messages from libchat
++ Use libchat as unified backend. Export all messages to libchat, and render messages from libchat
 + Search by uid/username
 + Skip existing files when copying android resources
 + Fix rare unhandled types: > 10000 and < 0
 + Use alias name in group chat, instead of id
-+ Better user experiences... see `grep 'TODO' lib -R`
++ Better user experiences... see `grep 'TODO' wechat -R`
 + more easy-to-use for non-programmers (GUI?)
