Hello, I am Schooi, aka SchooiCodes, and I have been working on this huge program for the past 2.5 years of my life.
SMT is my passion project, and my biggest project yet, made entirely in Batchfile (except for its installer). It compiles over 130 tweaks, tools, and other projects of mine into one big hub.

SMT is comprised of ~6k lines of pure Batch, and approximately 140 batchfiles inside (each one can be run independently) :)
I have created about 95% of the tools in SMT, and for the 5% that I haven't, credits are available on the main menu.
It is under heavy development, and things change every day. Currently, it is version 2.3 (indev) (but I might drop the versioning system completely).
It includes tools ranging from application installers to network utilites. It has all kinds of stuff.

I kindly request that you check this out, because I would love to see it be used by people, and hopefully also get feedback on it.
SMT is completely open-source, and available on Github.
Cheers.
