It's a kitchen sink even before you install any plugins, and yet all the useful functionality requires plugins.

All I want is a text editor that can quickly switch to another file, that doesn't make it annoying when the file it had open was changed, that only adds the input that I type to a file and nothing else.

Also easy integration with commandline tools (select text, pass that as stdin to a command, replace it with stdout, all done trivially without going through a billion menus and plugins), vertical selection and multi-cursor that doesn't suck, maybe a few other details, are things where it failed to deliver.
