I agree the current recall behavior is unintuitive, and often confusion, especially when using the J session as a scratch pad. When trying out different things, not paying too much attention to where you do the edit, all edited commands and their outputs are inconsistent, and thus useless. Of course, changing the default workflow will upset a lot of people.
A solution that eg. wxMaxima[1] has gone for is putting output belonging to changed commands in grey, marking the output as not corresponding with the command above. Executing the command in place replaces this output in the history with an updated version. This forced update could for instance be another shortcut (eg. ctrl-enter), without interfering with the "standard" way J's session works. I can imagine there's a fair amount of code going into implementing this, as it would mean keeping track of where which commands and their output are put, but I think it would be a nice addition which defuses this recurrent issue people seem to have with J. Either way, I'm open for brainstorming about this. A smaller thing which I would like when recalling stuff is that the cursor position would be saved when using Enter on a previous line to pull it down. A lot of times I automatically click where I want to edit a line, after having it pulled down. This would save some mouse or cursor key work. Also, I like the smart home key behavior (first going to the first non-space character before skipping to the real home). Could it be extended to also work when selecting stuff with shift-home?
