Paint your code with rainbow-highlighter.
After coding for a while, I just found out I just can't keep track of multiple variables at once.
With this plugin, you can keep easily track of many variables by colors.
Press shift+alt+z, and variables curser is on will be highlighted. Press the same command again to remove highlights.
Press shift+alt+a to remove all highlights.
rainbow-highlighter.palette: Set of colors that will be used for highlighting. rainbow-highlighter.background-alpha: If you're using background, this value will be the alpha value for background. rainbow-highlighter.use-border: Use border rather than background, like gif above.
