 - 2020.12.18: Support re-recognition of a single label box (by [ninetailskim](https://github.com/ninetailskim) ), perfect shortcut keys.
 
+### TODO:
+- Lock box mode: For the same scene data, the size and position of the locked detection box can be transferred between different pictures.
+- Experience optimization: Add undo, batch operation include move, copy, delete and so on, optimize the annotation process.
