To me, the editor has a lot of good things (Find and Replace, not having to re-link a word because it wasn't capitalized, cleaner layout, etc.), but it just feels janky for multiple reasons, for one, why does it keep highlighting nearby characters, and why when I need to rewrite something or fix a spelling error, the words seem to 'blend' together, the one I'm writing going over the pre-existing one.
This as an ability of the editor is quite.... Odd.
Why would I want the section I'm rewriting to delete the section after it? And what's the auto-highlight actually for? I see myself taking minutes longer just to fix one spelling error due to this, before then it took only around a second, around 10 if the word had a link attached.
Edit: This makes it much, much harder to fix miniscule things, I suspect the new editor was made almost solely with editing bigger sections or the entire page in mind, rather than smaller things such as grammar errors.
