You can add/remove packages (.zip-files) and extract them. There is already Hekate4 and 5 and the Appstore preinstalled.
For the payloads it uses TegraRcmSmash by @rajkosto
and the necessary drivers.
You can there as well add and remove payloads you want to use. Included packages so far here: biskeydump,fusee testpayload, hekate_ctcaer_2.0
I tested the homebrew launcher with hekate on my 4.1.0 Switch with a Windows 10 PC - everything worked out perfectly.
And yes people I know - this isn't groundbreaking, but an All In One Package and that exactly was what I wanted.
An updater is also included, so you should be notified once something new is available.
There is a installer version as well as a portable version. Just make sure to extract everything if you choose portable.
Linux integration will follow sometime later - maybe you even want to contribute to that.
