multiple cursors: is nothing compared to the confirm flag in `:%s/foo/bar/gc` + columnar editing in conjunction w/ something like tabularize

intelligent refactoring: is extremely unlikely to happen soon

customizble search directories: is way more flexible in a terminal than anything i've ever seen an IDE guru do. it's not vim though. it's vim + shell.

integrated terminal: you're already in the terminal, using tmux doubles down on the benefit

vim has way more flexible buffer pane layouts + tabs + sessions (IDE's also have sessions, but vim can do multiple sessions for a project). i've never seen an IDE with anything like the jump stack, marks, multiple yank registers, the flexibility of macros, or anything like `:r !$COMMAND` or for that matter `:w !$COMMAND`. basically no IDE has anything which matches vim's `NormalMode`. type aware code completion and syntax checking is available depending on the language.

these things aren't free though. you have to invest before they pay out.
