Using multiple plugins depending on the file types

[zeddo123]

Use case example

If a user was writing in both markdown and latex (for some reason), it would be much better to a plugin texcount and a markdown one working together instead to having to write a texcount-markdown plugin

Implementation

This is just from the top of my head, so very open to suggestions.

We could allow plugins to declare which files they would like to use, so when the user uses markdown and texcount we know which one will handle which file. And if the user only specifies one plugin we would pass all the files to the plugin?
