Add "Timeline" feature

[Mishasama]

Is your feature request related to a problem? Please describe.
Sometimes the content of the same text box will be rewritten over and over again, such as the chat text input box. If you want to go back to a previous point in time, you can't do it.

Describe the solution you'd like
Hopefully it can do something like Type Machine on Android.

Describe alternatives you've considered
Maybe just add a feature to automatically group different versions of entries in the same text box and then arrange them according to time.
