Thanks from a user ;) I cannot use any editor without vim keybindings, furthermore I love "relativenumber", however VSCode gives no API for relative numbers (there is some hacky gutter images extension, but it is really hacky, slow and bad looking). I've made a fork with relative numbers built-in https://github.com/alfanick/vscode. Not going to do pull request, at least not yet - unit testing and i18n required.
BTW I do not use TypeScript (or JS), but it was quite easy to write, still I was quite surprissed how messy VS Code codebase is.
The reason that plugin lags is because it was using `setInterval` initially but I changed it to selectionChange hook and now it works smoothly. Now the only problem with it is it hides breakpoints but definitely we will improve this experience later on. / I'm a Code team member*/
I find relative number very useful to jump lines. Please consider showing current line number for current line. And go ahead with the pull request, many of us need this feature :)
