Sort of uses units by Low Level to High Level

[EMBBlaster]

As you added sort of uses units. Could them be sorted by Level?
I mean RTL first, then VCL units, then packages units then your project units as this comment.
See also this python script.

And maybe it would be good to uderscore (by some color) the units in the interface section, which can be moved to the implementation section? :-)

it's a good idea by the way (both)
I'm not implementing anything else in this source code, because I'm creating something new to handle better the necessities, it's taking time.
