@hellresistor what do you think about commit messages? :) we can use similar format to separate each commit by "mini features"

<type>(<scope>): <subject>

Type

Must be one of the following:

• feat: A new feature
• fix: A bug fix
• ... There are more options in the reference link below

Scope

The scope could be anything specifying place of the commit change. I choose the folder of the edited files or the development context usually

Subject

The subject contains succinct description of the change

This idea comes from angularjs commit message format

I am preparing a feature, but being hard :X Almost There :X but an "almost" to much bigger :X
