@sbraun I'm still discovering more as I use it; most of it easy to change/update/reset, so am not complaining. Just surprised by it.
Also, to preface this, I am not an evil-mode user, and prefer regular Emacs bindings.
Current list:
1. `+default-want-RET-continue-comments`
2. C-a and C-e not behaving as they would on Vanilla emacs
3. tab-always-indent behavior: I quite like the Emacs default of reindenting from anywhere on the line (i.e., `t`). I can understand why this default was changed though, but I am surprised it is changed to `nil` rather than `complete` which might make more sense for newcomers.
4. smartparens on by default: I don't quite care for it; there is a `+smartparens` in `init.el`, but removing it doesn't disable it (instead just disables some configuration of it). Actually disabling it requires setting up a hook (I later found out that the FAQ does have instructions for this, but if it needed an FAQ, maybe there should've been something easily toggleable, or at least a pointer to the FAQ for newcomers?)
5. undo changed: I find vanilla emacs's undo more powerful, and for newcomers I'd be surprised if they'd ever even find or realize that undo can be more powerful. I know vanilla undo is a tiny bit surprising for folks, but imho that lasts only for a short while before realizing how useful it really is.
6. `~` in IDO being unnecessarily bound, making typing `C-x C-f ~/foo` not work as expected. IDO already has support for `~/`, so I am not sure why `~` is being bound the way it is.
