Shameless plug: Elvish is a shell with a filesystem navigator built in - you can see it in demo 5 on the homepage https://elv.sh
autosuggestion: type something and then suggest a command from the history that matches what i typed.
non-incremental history: if the autosuggestion is not the right one, use arrow keys to search for a better one.
fish has both.
zsh has a module for autosuggestion. but if the suggestion is wrong then i have start search and retype what i just wrote. i want to avoid having to type twice.
another feature i am looking for is renaming files in place:
instead of: 'mv oldname newname;' i want something like 'rename oldname; enter;' and now allow me to edit 'oldname' into 'newname'. very often the filenames are long and i only want to change a few characters in it. having to retype the whole filepath when using mv can lead to errors.
If you use bash, or any readline-based command line (in emacs mode):
mv long.file.name |^W^Y^Y
mv long.file.name long.file.name |
edit: and if your filename has spaces, replace the ^W above with M-C-b C-k

and

that's pretty much what i had in mind, but only for a single rename.
i just did a search and embarrassingly discovered imv which is part of the renameutils package which also contains qmv, a tool to batch rename lots of files by loading the list into an editor. embarrassed because qmv is my favourite tool for batch renaming, and so i have it already installed.
imv is exactly what i am looking for, for the single file rename case: "The imv ("interactive move") program, is trivial but useful when you are too lazy to type (or even complete) the name of the file to rename twice. It allows a file name to be edited in the terminal using the GNU Readline library."
so we can consider this problem solved.
back to alternative shells: i am just spoiled by fish (no the fish isn't spoiled): autosuggestion and non-incremental search like fish are a requirement for me to consider any other shell now.
btw: autosuggestion for elvish is being discussed here: https://github.com/elves/elvish/issues/322 and apparently it has some of that search feature too (from a comment): "type the beginning of a command and press Up and cycle through all the commands that start with the string I typed."
i am going to have to try that.
There's also Ctrl-R for searching through history, and unlike other shells it has a list UI (like fzf). If you've typed something and then press Ctrl-R, it gets used as the filter.
