I know this is pretty opinionated feature request but it would be awesome if VSCodeVIm could provide Select Mode similar to Sublime Vintageous.

I've come from Sublime and this is the feature I've used a lot and am really missing in Code's Vim. How it works: after enabling Select Mode via gh you can use different keys to effectively navigate selections (e.g add cursor for a match with j or skip current selection with k). Though seeing it in action is worth a thousand words; it's really handy and powerful synergy of Vim and multi-cursor mode.

Read the linked Vintageous Select Mode description first, then inspect VSCodeVim's TypeScript keybinding and selection-handling areas. Verify the intended behavior for enabling Select Mode with gh, adding a cursor with j, and skipping a selection with k. Done means the mode and its navigation behavior work consistently with VSCodeVim's existing Vim and multi-cursor behavior.
