undolist builtin (maybe even a session builtin)

[zenhog]

I think the tilte suffices, a jump list builtin with file preview and undolist builtin with vimdiff preview could be an interesting additional default feature. Perhaps also a session builtin for vim sessions.

The undolist is kinda hard as it is a tree not a list. But I like the jumplist.

Jumplist is in master. I am not sure about the undolist tho.

You might want to use this for undo https://github.com/mbbill/undotree

For session you can use this session manager: https://github.com/Shatur/neovim-session-manager
For undotree: https://github.com/mbbill/undotree

Closing for now
