How can I make undo-tree to get the diff rather that modifying the whole buffer

[ABDsheikho]

Since I started migrating from telescope to fzf-lua, I've been very pleased
that fzf-lua provides the Undo-Tree feature without requiring any extensions,
as I relied heavily on it.

With telescope I was using telescope-undo which provided the ability to restore the whole buffer, and yank the diff (added/removed). And I believe that this is a killer feature.

Until now I'm still using telescope-undo, and when I use fzf-lua's undo-tree
I just move the cursor to the preview window and select what I want to yank.
However, I plan to remove telescope-undo and implement this feature in fzf-lua.

• Is it possible?
• How do I start? (probably I'll write it from scratch)
• Is it good feature that it can be requested as a feature for fzf-lua?

Anything is possible

How do I start? (probably I'll write it from scratch)

Stat with this file, everything is there related to undo:

Is it good feature that it can be requested as a feature for fzf-lua?

If the workflow is seamless and not intrusive, that would depend how you’ll implement it
