Editing scrollback is possible in eshell, and something I use often.
replyAh. I tested it before but now I see that I have
`(setq eshell-scroll-to-bottom-on-input 'all)` in my config which always snapped point back to the prompt when I tried to edit the scrollback.
replyAnyway, unfortunately that is not possible in a Ghostel buffer and most likely also will never be. I'm open to ideas though how we could improve or replicate your eshell workflow.
But also, eshell is awesome and Ghostel is not a replacement for it. It's more a replacement for term.el, maybe shell.el (with line-mode) and other terminal packages like eat and vterm.
I think issue #426[0] would be sufficient, since it would allow for editing after the command is finished. I understand that it probably won't happen any time soon, but embedding a full terminal emulator in Eshell is the thing that's got me staying on EAT right now.
replyGhostel looks really nice though!
