Make mode is the new feature came in this plugin on commit a96ed3c84c.
It’s an extension of the previous features, but is also built on two main components:

1. Project: it represents the target dir on which we can execute commands; to make this variable available on the system, it has been registered in the metadata environment (defined locally for each session) as @quickfix-project

2. Make command: as described for the project variable, this is just the command to be executed on project target dir. It is defined as @quickfix-make and users can change its value according to the kind of project they’re working on.

This is a new mode of work and as usual, metatada are setted up and queried on every new execution.
Modifying these values:

tmux set-option @quickfix-project "/target/dir/"

and

tmux set-option @quickfix-make "make command"

users can obtain the desidered behaviour related to the category of their project. </br> An example is show by the following video.
