Override a Plugin

Hello, I am new in here but I do have a background like programmer.
My question is simple: 

  1. Can I ovveride a Plugin like, Maps, salesforce_connector or other?
  2. If is It possible, and if I ovveride them, do I loose any type of assistance or what?

You can create a clone of this plugin, you keep the original plugin and can use and change your clone.

Whats can happens is to lose the atualizations the plugin, because you are use the clone of plugin.

But yes, you can override this plugin.
