Checklist

You have to check all before open issue.

• [x ] Provide your environment info clipped by Vim Mode Plus: Clip Debug Info command.
• [x ] Try with latest Atom and latest vim-mode-plus.
• [x ] Pick a descriptive and non-ambiguous subject
• [x ] Express "what" you want(feature? config option?, behavior change?) in short sentence(not long!).
• [x ] Contrast current behavior if you want to change current behavior, with sample text, operation(keystroke) and result.
• [x ] Include real use case so that maintainer can understand "why" you need help.
• [x ] Include Atom(atom --version), vim-mode-plus version, and OS version(e.g. macOS Sierra 10.12.3).
• [x ] If keybinding issue, Read this.

macOS Catalina 10.15.5

When typing tab in insert mode, it does nothing. I've deleted everything in my Keymap. Disabling atom-vim-mode-plus allows the correct behavior, but once it's installed, I can't type tab and have it do anything.

I'm not having this problem in my version.
