https://atom.io/packages/vmp-gutter-annotate-mark
A plugin for vim-mode-plus that adds a mark specific class to the gutter so that it can be specially styled.
This plugin needs the excellent vim-mode-plus plugin. Once you've installed both, set marks as usual (with m). Your gutter will now show the name of the mark in orange.
Included is a "literal" theme which marks the gutter literally, i.e. it puts the name of the mark in the gutter. You can overwrite this in your user stylesheet to suit your preference.
Currently, the plugin only annotates for alphabetical marks ([a-z]), as it's clearer when putting the name of the mark in the gutter. Future themes and settings could potentially allow more or all marks to be annotated in the gutter.
- For lines with multiple marks, it only shows the highest alphabetical value (z > y).
